"Find the measure of each angle in the following diagram"

Answers

Answer:

Each angle is 60°

Step-by-step explanation:

The 2 angles are equal to each other because they're alternate exterior angles:

10x - 20 = 7x + 4

10x - 7x = 4 + 20

3x = 24

x = 8

10x - 20

10(8) - 20

80 - 20

60

Since these angles are exterior angles, their angle measures are equal so they both are 60°

60 degrees is the measurement of each angle :)

HELP PLEASEEE :) TY TYYYYY

Answers

Answer:

A = 8, B = 6, C = 4 , D = 7

Top = 29

Side = 20

Step-by-step explanation:

Last row : A + A + A + A = 32 ==> A = 8

First row : D + A + D + D = 3D + 8 = 29

                                          3D = 21 ==> D = 7

Second row : B + D + A + B = 27 ==> 2B + 7 + 8 = 27

                                                          2B = 12 ==> B = 6

Third column : D + A + C + A = 27

                      7 + 8 + C + 8  = 27 ==> C = 4

Answer:

h=square root of 55

area of triangle=15*square root of 5

Step-by-step explanation:

Answer:

a. 7.4 cm

b. 22.2 cm²

Step-by-step explanation:

a. Apply Pythagorean theorem to find h.

c² = a² + b²

Where,

c = 8 cm

a = 3 cm

b = h cm = ?

Plug in the values

8² = 3² + h²

64 = 9 + h²

64 - 9 = h²

55 = h²

h = √55

h ≈ 7.4 cm

b. Area of the triangle = ½*bh

b = 6 cm

h = 7.4 cm

Area = ½*6*7.4

Area = 22.2 cm²

[tex]80\:\mathrm{km^2}[/tex]

Step-by-step explanation:

The area of a triangle can be given by [tex]A=\frac{1}{2}bh[/tex], where [tex]b[/tex] is the base of the triangle and [tex]h[/tex] is the height of the triangle.

As marked in the diagram, we are given the following:

Base of 10Height of 16

[tex]A=\frac{1}{2}bh=\frac{1}{2}\cdot 10\cdot 16=\boxed{80\:\mathrm{km^2}}[/tex]

Answer:

Hello! answer: 80 km

Step-by-step explanation:

To find area in triangles you can do

base × height ÷ 2 or base × height × 1/2

10 × 16 = 80 therefore the area is 80 km
