Answer:
A
Step-by-step explanation:
x = 37.5 (or)
Solution:
Given .
Let us take BE = x and BC = 25 + x.
To determine the value of x:
If two triangles are similar then the corresponding angles are congruent and the corresponding sides are in proportion.
Do cross multiplication, we get
Subtract 30x from both sides of the equation.
Divide by 20 on both sides of the equation, we get
x = 37.5 (or)
Hence the value of x is 37.5 or .
Answer:
Step-by-step explanation:
If COP and TOD are vertical angles, then they are equal to each other because vertical angles are equal.
m COP = m TOD
Given
COP = 11x - 17
TOD = 9x + 11.
Substitute:
11x-17 = 9x+11
11x-9x = 11+17
2x = 28
x = 28/2
x = 14
Get <COD
<COP = 11(14)-17
<COP = 154-17
<COP = 137
<COD = 180-<COP
<COD = 180-137
<COD = 43°
Similarly:
<POT = 180 - <TOD
<POT = 180 - [9(14)+11]
<POT = 180 - 137
<POT = 43°
Answer:
x³ - 3x² + 10x + 3 +
Step-by-step explanation:
Using synthetic division to divide by x - 1
1 | 1 - 4 13 - 7 3
↓ 1 - 3 10 3
----------------------------
1 - 3 10 3 6 ← remainder = 6
--------------------
↑ quotient
= x³ - 3x² + 10x + 3 +
The second equation is y=5x+2
