Answer:
91 cm^2
Step-by-step explanation:
The bottom rectangle has an area of
A = l*w = 5* 14 =70
The top right rectangle has an area of
A = 3 *7 = 21
Add the areas together
A = 70+21 = 91 cm^2
Answer:
the answer is 20
Step-by-step explanation:
20/2= 10. 10-6= 4.
F(-2)=(-2-1)^2+3(-2)
=9-6
=3
Hence, ans is 2
Answer:
67.5°, 107.5°
Step-by-step explanation:
For supplementary angles, their sum equals 180°.
Let x be the first angle and y be the second angle, then
x + y = 180°.
It is given that x = y + 45°.
So x + y = 180°
substituting x into the equation, we have
y + 45° + y = 180°
simplifying, we have
2y + 45° = 180°
collecting like terms, we have
2y = 180° - 45°
2y = 135°
dividing through by 2, we have
y = 135°/2
y = 67.5°
Since y = 67.5°
then x = y + 45°
x = 67.5° + 45°
x = 107.5°
