Answer:
x = 35
Step-by-step explanation:
Since they are vertical angles, the angles are congruent and therefore you can set them equal to each other.
4x + 20 = 3x + 55
Have x on one side of the equation by subtracting 3x from both sides.
x + 20 = 55
Subtract 20 from both sides of the equation.
x = 35
Answer:
16 square units
Step-by-step explanation:
→ Find the area of the whole triangle
0.5 × ( 5 + 4 ) × 8 = 36
→ Find the area of the small triangle
0.5 × 5 × 8 = 20
→ Minus the area's of the triangles
36 - 20 = 16 square units
