Answer:
h = 6 cm
Step-by-step explanation:
Atriangle = b×h/2
18cm² = 6cm×h/2
36cm² = 6cm×h
h = 36cm²/6cm
h = 6 cm
Answer:
a ≈ 8.9
Step-by-step explanation:
Set up the equation as so:
8a^2 + 2 = 634
First, subtract two from both sides:
8a^2 = 632
Then, divide by 8 to further isolate the variable.
a^2 = 79
To get rid of the squared, you have to take the square root of both sides. The square root of 79 is roughly 8.9. Ergo, a ≈ 8.9
