Answer:20
5x add 3x is 8x 12 + 8 is 20 so 8x + 20 = 180 because it’s a straight line so 180-20 is 160 then divide 160 by 8 to work out 1 x rather than 8 x which is 20

Answer:

Step-by-step explanation:

This is an isosceles triangle so the two down angles are equal

(5x+12) + (3x+8) = 180° (angle on a straight line is equal 180°)

Open brackets

5x+12 + 3x+8 = 180

8x + 20 = 180

Collecting like terms

8x = 180 - 20

8x = 160

Dividing by 8

x = 160/8

x = 20°

Thr four angles of a quadrilateral L are in the ratio 5:2:3:8find the angle
Anuta_ua [19.1K]
Ratio = 5:2:3:8
Sum of all internal angles = 360°
5x + 2x + 3x + 8x = 360°
18x = 360°
x = 20°
Therefore,
5x = 100°
2x = 40°
3x = 60°
8x = 160°
5:2:3:8 :: 100:40:60:160.

NEED HELP!!!!!EMERGENCY
Basile [38]

Answer:

49.5 square inches

Step-by-step explanation:

We can split the figure into two easier shapes to find the area of; a triangle and a square.

The formula for a triangle is (b*h)1/2. Once we solve we get 24.5 or 24 1/2.

The formula for a square is l*w. Once we solve we get 25.

To find the area of the shaded region, we would add both area and get 49.5 or 49 1/2 square inches.
