Answer:
B. acute, isosceles
Step-by-step explanation:
The two small lines intersecting the two sides stand for congruency.
Two sides are congruent, so this is an isosceles triangle.
None of the angles here are greater or equal to 90 degrees, so it is an acute triangle.
Please mark brainliest!
Answer:
B. Acute, isosceles
Step-by-step explanation:
Angles can be classified by both their sides and angles. There are 3 classification for each measurement, making 6 total classifications. This includes acute, right, and obtuse for angles and isosceles, scalene, and equilateral for sides.
Sides
The tic marks on 2 sides on the side show that they are congruent. Any triangle that has 2 congruent sides is classified as isosceles.
An additional fact is that the angles opposite of the congruent sides are also congruent. This information is not pertinent to this question, but might be useful in the future.
Angles
A triangle's classification for its angles is always based on the largest angle in the triangle. In this case, the largest angle is an acute angle. Remember that an acute angle is less than 90 degrees. This means that the triangle is acute.

Find the unknown angles of triangles.
Please help me...!!!
Answers
Let's take this fun problem step-by-step:
Let's first analyze the triangle: ΔBRE
∠B + ∠E + ∠R = 180
45 + 35 + ∠R = 180
∠R = 100 ⇒ ∠BRE = 100 degrees
Now let's analyze ΔAQD
∠A + ∠Q + ∠D = 180
30 + ∠Q + 50 = 180
∠Q = 100 degrees ⇒ ∠AQD = 180 degrees
Now let's consider another fact:
AQC is a straight line⇒ meaning that ∠AQD + ∠RQC = 180 degrees
⇒ ∠RQC = 180 degrees - ∠AQD = 180 - 100 = 80 degrees
CRE is a straight line⇒ meaning that ∠BRE + ∠BRC = 180 degrees
⇔ ∠BRC = 180 degrees - ∠BRE = 180 - 100 = 80 degrees
Now let's consider ΔQRC:
∠BRC + ∠RQC + ∠QCR = 180 degrees
80 + 80 + x = 180
x = 20 degrees
Answer: 20 degrees

. The depth of the Atlantic Ocean at a channel buoy off the coast of
Maine can be modeled by y = 5 - 3cos (pi/6t) where y is the water depth
in feet and t is the time in hours. Consider a day in which t=0
represents 12:00 midnight.
a. For that day (in 24 hours), when do the high and low tides occur?
b. What are the respective depths of the ocean at high tides and low
tides?
Answers
a)The high and low tides occur at when the value of cos function is an odd and even multiple of the π respectively.
b)The respective depths of the ocean at high tides and low tides will be 8 ft and 2 ft.
What exactly is a function?A function is a statement, rule, or law that specifies the connection between two variables. Functions are common in mathematics and are required for the formulation of physical connections.
Modeling the depth of the Atlantic Ocean at a channel buoy off the coast of Maine is;
[tex]\rm y = 5-3 cos (\frac{\pi}{6} t)[/tex]
a) High tide's value of 'y' when the value of y is maximum. value of cosine is minimum.
The minimum value of cosθ = 1.
The standard form to write the cos function is as;
θ=(2n+1)π
Whenever. high tides occur when it equals odd multiples of π. Similarly, at a Value of even multiples of even function, low tides are at their peak.
Hence,the high and low tides occur at when the value of cos function is an odd and even multiple of the π respectively.
At high tide;
соsӨ = - 1 (min value)
y= 5-3(-1)
y = 5+3
y=8 ft
At low tide,соsӨ = + 1 (max value)
y =5-3(1)
y= 5-3
y= 2
Hence,the respective depths of the ocean at high tides and low tides will be 8 ft and 2 ft.
