Answer:
D. t = -1
step-by-step explanation:
that side should be 180 degrees and the whole is 360 but we are only measuring half
so (20t + 5) = 15t
-20t -20t
5 = -5t
/-5 /-5
-1 = t
Answer/Step-by-step explanation:
The corresponding segments of two similar figures are always proportional to each other. I'm other words, the ratio of their corresponding segments are equal.
The figures shown above in this question are not similar figures because their segments are not proportional to each other.
This is because:
DE/KL ≠ FG/MN
DE = 2 units
KL = 1 unit
FG = 1 unit
MN = 1 unit
DE/KL = 2/1 = 2
FG/MN = 1/1 = 1
Thus, DE/KL ≠ FG/MN.
Therefore, the figures are not similar.

<u>Formula Evaluation</u>
Formulas are expressions where a sequence of letters, numbers or symbols have a determined meaning in given system.
Formulas are usually expressed as mathematical operations that connect one or more variables.
The perimeter of a triangle is the sum of the lengths of its sides. Being a,b, and c their sides, then the perimeter has the formula

We are given the values of



Thus the perimeter is


D=11.25
You can make a proportion of the bigger triangle to the smaller triangle
8/15=6/d
cross multiply
8d=90
d=11.25<span />
Step-by-step explanation:
4x² - 3x - 2 = 0
0 = 4x² - 3x - 2
0 = 16x - 3x - 2
0 = 13 x -
