Answer 1

Answer:

x = 36°

Step-by-step explanation:

There are 180° on a line so 180° - 126° = 54°

54° is one of the angles and so is 90° (because it is a right angle)

Therefore, now we know that x = 180° - (54° + 90°)

54° + 90° = 144°

180° - 144° = 36°

x = 36°

Answer 2

Answer:

x = 36

Step-by-step explanation:

solution:

we have given,

            in the right angled triangle.

             exterior angle = [tex]126^{o}[/tex]

we know,

          exterior angle = sum of interior non adjacent angle

   so,   [tex]126^o[/tex] = [tex]x + 90^o[/tex]    [∵ one angle of right angled triangle is [tex]90^o[/tex]]

     or,  [tex]x = 126^o - 90^o\\[/tex]

     or,  [tex]x = 36^o[/tex]

hence, the value of x is [tex]36^o[/tex]

The values of P and Q are 270 units and 367 units respectively.

What is Pythagoras's theorem?

In a right-angled triangle, the sum of the squares of the smaller two sides of a right-angle triangle is equal to the square of the largest side.

We know, From Pythagoras's theorem hypotenuse² = base² + height².

So, p² = 179² + 203².

p = [tex]\sqrt{179^2 + 203^2[/tex].

p = [tex]\sqrt{32041 + 41209[/tex].

p = [tex]\sqrt{73250[/tex].

p = 270.

Now, we can find q.

q = [tex]\sqrt{250^2 + 270^2[/tex].

q = [tex]\sqrt{62500 + 72900[/tex].

q = [tex]\sqrt{135400[/tex].

q = 367.

find the shaded area

Answers

Answer:

88.85 Sq m

Step-by-step explanation:

For rectangle:

Length = 18 - 7.8 = 10.2 m

Width = 7.8 m

For both semicircular arcs:

Radius (r) = 7.8/2 = 3.9 m

Area of the shaded region = Area of rectangle + 2*Area of a semicircle - Area of circle with radius 3.5 m

[tex] = lb + 2 \times \frac{1}{2} \pi \times {(3.9)}^{2} - \pi \times {(3.5)}^{2} \\ \\ = 10.2 \times 7.8 + \pi \{{(3.9)}^{2} - (3.5)^{2} \} \\ \\ = 79.56 + \pi {(3.9 + 3.5)} (3.9 - 3.5) \\ \\ = 79.56 + 3.14 \times 7.4 \times 0.4 \\ \\ = 79.56 + 9.2944 \\ \\ = 88.8544 \\ \\ \approx 88.85 \: {m}^{2} [/tex]

m is the slope.

Start at (0, 2), the y-intercept. Go down 2 units and right 1 unit.

That is a rise of -2 and a run of 1.

m = slope = rise/run = -2/1 = -2
