Answer:

The value of a is 25

Step-by-step explanation:

When two angles are supplementary, they add up to 180 degrees

Mathematically,

(30 + 2a) + (125-a) = 180

30 + 2a + 125 - a = 180

a + 155 = 180

a = 180-155

a = 25 degrees

Triss [41]
Surface area of a prism=2(long x wide)+2(long x high )+2(wide x high)
Data:
long=5 m
wide=2 m
high=2 m

Surface area of this prism=2(5 m * 2 m)+2(5 m*2 m)+2(2 m*2m)
=2(10 m ²)+2(10 m²)+2(4 m²)

I need help with problem
topjm [15]
D + q = 40
.10d +.25q= $7.75

d +q = 40
d =40-q
.10(40-q) +.25q= $7.75
4 - .10q + .25q =7.75
4 +.15q =7.75
4-4 +.15q =7.75-4
.15q= 3.75
.15q/.15 = 3.75/.15
q = 25

d =40-25
d = 15

Check
.10(15) +.25(25)= $7.75
1.5+6.25=7.75
7.75=7.75
