Answer:
V≈ 863.27 in³
Step-by-step explanation:
Answer: $5
Step-by-step explanation: This can be represented by the equation
40 + 12T = 25 + 15T
We just solve for T.
Subtract 12T from both sides
40 = 25 + 3T Subtract 25
15 = 3T Divide by 3
5 = T
Answer:
60
Step-by-step explanation:
<C+<D = 180 since they form a straight line
5x+20 +3x = 180
8x+20 = 180
Subtract 20 from each side
8x+20-20 = 180-20
8x = 160
Divide by 8
8x/8 = 160/8
x = 20
We want to find angle D
<D = 3x= 3*20 = 60
Answer:
See below
Step-by-step explanation:
15)
In the right-angle triangle, once one of the angles is 44º, then, the unknown angle is
.



The angle
of the other triangle plus the angle
of the right-angle triangle is equal to 90º, therefore they are complementary angles.
So,



To find ?, we have



16)
The sum of the internal angles of the triangle with angles 50º and 25º is equal to 180º, therefore, the other angle is

Once the angles are opposite, they are the same. For the triangle with the 36º angle, we have
