Answer:
the answers are 13, ab/2, 20 and 15x²/2
1/2 a^2, 1/2 b*a , 20, 7.5x^2
Step-by-step explanation:
Area of right angle triangle = 1/2 height * base so
Area of MSP = 1/2 a^2 , Area of BUC =1/2 a*b
Area of BAC =1/2 8*5 , Area of DRK =1/2 3x*5x =1/2 *15x =7.5x^2
z = 2
y = 5
3.14 million
10.676 - 7.536 = 3.14
To check
7.536 + 3.14 = 10.676

135 meters
h = 60t - 5t²
t is in seconds and it says to find out the height after 3 seconds
Sub the value '3' into 't'
h = 60(3) - 5(3)²
h = 180 - 5(9)
h = 180 - 45
h = 135 m
