Answer:
x=64
Step-by-step explanation:
Both the semicircle that says 180, and the right angle sign in the image serve to support the idea that all parts of the figure equal 90
Therefore, it is safe to say that you need to subtract 26 from 90 in order to solve for x.
90-26 = 64
Step-by-step explanation:
sin 0 = opposite ÷ hypothenus
sin 0 = 3 / 5
3 / 5 = x / 15
5 × n = 15
n = 3
x = 3 × 3 = 9
y = use pythagoras
= 12
tan 0 = opposite ÷ adjacent
tan 0 = 9/12
Formula: A = pi(r)^2
1/4(2)^2pi
1/4 * 4 pi = just pi
The area would be 3.14
NUMBER 2 is 240 because 6 times 4 times 10 is equal to 240. I am still working on the others
