Answer:
a ) x = 3
b ) 70
c ) 50
Step-by-step explanation:
( 15x + 5 ) and ( 22x + 4 ) are interior angles.
120 is the exterior angles.
Formula : -
Sum of two interior angles = Exterior angle
15x + 5 + 22x + 4 = 120
15x + 22x + 5 + 4 = 120
37x + 9 = 120
37x = 120 - 9
37x = 111
x = 111 / 37
x = 3
Therefore,
x = 3
Angle B
= 22x + 4
Substitute x = 3,
22x + 4
= 22 ( 3 ) + 4
= 66 + 4
= 70
Therefore,
the measure of angle B is 70.
Angle C
= 15x + 5
= 15 ( 3 ) + 5
= 45 + 5
= 50
Therefore,
the measure of angle C is 50.
The answer is <span>length = 10 yd, width = 2 yd
proof
</span><span>The length of the playground is 5 times longer than its width, it means
l=5w, but 10= 2x5 so we can write l= 5w,
and Area = 20 =l x w = (5x2) x 2 =20</span>
Answer:
-10x +25
Step-by-step explanation:
–5(2x – 5)
Distribute
-5 * 2x - (-5) * 5
-10x +25
Start: 10:50 am
Plus the 20 minutes would be 11:10 am
11:10 am plus the 14 minutes would be 11:24 am
The end time is 11:24 a.m.
And the elapsed time would be a total of 34 minutes
V = 60 as the triangle is looking like a equilateral triangle
