Answer:
45
Step-by-step explanation:
To find the area of any right triangle, meaning a triangle with a right angle, you use 1/2 base x height
So... here the base is 9 and the height is 10
Therefore: 1/2 x (9) x (10)
1/2 x 90
= 45
Answer:
x = 80°
Step-by-step explanation:
Angle on a straight line = 180°
(x + 40)° + (x - 20)° = 180°
x + 40° + x - 20° = 180°
2x + 20° = 180°
2x = 180° - 20°
2x = 160°
x = 160°/2
x = 80°
Check:
(x + 40)° + (x - 20)° = 180°
(80° + 40°) + (80° - 20°) = 180°
120° + 60° = 180°
180° = 180°
