A and C=58°
B= 58°

You can tell that the triangle is isosceles because of the two congruent sides. In an isosceles triangle, when two sides are congruent, their corresponding angles also are. So by that, you can determine A=C. You then set up the equations equal to each other.

5x+16 = 2x +43
3x+16 = 43
3x = 37
x=9

Then, plug x in.

5(9) + 16 = 61

and

2(9)+43 = 61

After that, you can add up 61 and 61, which equals 122. All triangles add up to 180, so you would do 180-122.

180-122 = 58, so A and C = 61 and C= 58.

Can someone help me with this

Anastasy [175]

Answer:

Yes

sum of angle = 180°

First diagram

R+D+E=180°

110°+28°+E=180°

138°+E=180°

E=180°-138°

E=42°

Second diagram

T+V+A=180°

T+28°+42°=180°

T+70°=180°

T=180°-70°

T=110°

What is the diameter of circle T?

Ratling [72]

Answer:

$Diameter = 16$

Step-by-step explanation:

Given

$\theta = 72$

$Sector = \frac{64}{5}\pi$

Required

Calculate the diameter

The area of a sector is:

$Area = \frac{\theta}{360} * \pi r^2$

Substitute values for Area and $\theta$

$\frac{64}{5}\pi = \frac{72}{360} * \pi r^2$

Divide both sides by $\pi$

$\frac{64}{5} = \frac{72}{360} * r^2$

Make $r^2$ the subject

$\frac{64*360}{5*72} = r^2$

$\frac{64*360}{360} = r^2$

$64 = r^2$

Take positive square roots of both sides

$\sqrt{64} = r$

$8 = r$

$r = 8$

The diameter is then calculated as:

$Diameter = 2r$

$Diameter = 2*8$

$Diameter = 16$

Answer:

Rectangle: 112m

Trapezoid: 28m

Step-by-step explanation:

The area of the rectangle is 8*14, which is 112. The area of the trapezoid is ((base1 + base2)* height)/2. That is ((4+10)*4)/2, which is 28.
