What Is The Value Of X? Please Help

Answers

Answer 1
Answer: x = 23

Steps:
180 - 100 = 80

51 + 80 + (2x+3) = 180
131 + (2x + 3) = 180
2x + 3 = 49
2x = 46
x = 23

2x + 3
2(23) + 3
46 + 3
49

Check:
49 + 51 + 80 = 180
180 = 180 ✅

Can you please help me solve for x for this triangle please!!

Answers

X=17.


Hope this helps

Answer:

See below, please!

Step-by-step explanation:

Since this triangle is a right triangle, the two acute angles are always going to be complementary (adding up to 90 degrees). So we can set up an equation: 2x+3x+5=90. Solve this and we get x=17.

Which proportion can be used to find the arc length, s, in units?

Answers

Answer:

Option B

Step-by-step explanation:

Formula to be used to calculate the length of an arc,

Length of arc = [tex]\frac{\theta}{360}(2\pi r)[/tex]

Here, θ = Angle subtended at the center by the arc

r = radius of the circle

By substituting values in the formula,

s = [tex]\frac{150}{360}(2\pi )(42)[/tex]

[tex]\frac{s}{2\times 42\pi }=\frac{150}{360}(\frac{2\times 24\pi }{2\times 24\pi } )[/tex]

[tex]\frac{s}{84 \pi }=\frac{150}{360}[/tex]

Therefore, Option B will be the answer.

| 4r - 12 | , if r < 3
Rewrite this expression without using absolute value
I nEeD hElP qUiCk!

Answers

Answer:

Step-by-step explanation:

Normally when you are doing an absolute value question, you do it like this

y = abs(4x - 12) and you write the absolute value equation as

y = 4x - 12 and

y = - 4x + 12

These two are shown in graph27a

to show both wings of the absolute value curve

This is slightly different.

I think you would write this as

y = 4x - 12 {r <3} where the restriction is outside the equation written with curly brackets. You should see both graphs together. The discussion of r<3 is shown in graph 27b
