Answer:
<A = 67
Step-by-step explanation:
The three angles of a triangle add up to 180 degrees. We know a right angle is 90 degrees.
<A + <B + <C = 180
3x-8 + 90 + x-2 =180
Combine like terms
4x-10+90 = 180
4x+80 =180
Subtract 80 from each side
4x+80-80=180-80
4x=100
Divide each side by 4
4x/4 = 100/4
x=25
But we want to know <A
<A = 3x-8
Substitute x=25
=3(25) -8
=75-8
= 67

The arc length is 12.56 m
Answer:
-1/4
Step-by-step explanation:
-1/2 + -1/4 = -3/4
This means each item increments by -1/4
We can do -1/2 + 1/4 to get -1/4
Yes,
10 x 5 = 50
4 x 5 = 20
They both have equal multiples.
