Answer:
see explanation
Step-by-step explanation:
3x and 144 are adjacent angles on a straight line and sum to 180°
3x + 144 = 180 ( subtract 144 from both sides )
3x = 36 ← value of 3x
divide both sides by 3
x = 12
and
2y - 5 and 95 are vertically opposite angles and are congruent, so
2y - 5 = 95 ← value of 2y - 5
add 5 to both sides
2y = 100 ( divide both sides by 2 )
y = 50
Then
x + y = 12 + 50 = 62
This composite figure consists of a right triangle and semicircle
The area of a triangle is: 1/2(bh)
The area of a semicircle is 1/2(pi)(r²)
Plug in the values:
1/2( 12)(8)
=48
1/2(3.14)(4²)
=25.12
25.12+48=73.12
Hope this helped :)
Answer:
36.67
Step-by-step explanation:
11/5=2.2
let the unknown no be x
6% of x=2.2
6/100 * x = 2.2
6x = 2.2*100
x = 220/6
x= 36.67
