Answer:
<em>Measure of angle B: 76°</em>
<em>Measure of angle C: 76°</em>
<em>Measure of angle A: 28°</em>
Step-by-step explanation:
<u>Equations</u>
Let's call
x = measure of angle B
Since angle B is congruent with angle C:
x = measure of angle C
The sum of the angles in a triangle is 180°:
180 - x - x = 180 - 2x = measure of angle A
It's given the measure of angle B is 20 more than twice the measure of angle A, thus:
x = 20 + 2(180 - 2x)
Operating the parentheses:
x = 20 + 360 - 4x
Adding 4x:
5x = 380
Dividing by 5:
x = 380/5
x = 76°
Measure of angle B: 76°
Measure of angle C: 76°
Measure of angle A: 180 - 2*76°= 28°

Answer:
Value of x = 19.42 unit (Approx)
Step-by-step explanation:
Given:
Base = 6 unit
Angle θ = 72°
Find:
Value of x
Computation:
Cos θ = base / Hypotenuse
Cos 72° = 6 / x
0.3090 = 6 / x
x = 19.4174
Value of x = 19.42 unit (Approx)
Answer:
N= 4
Step-by-step explanation:
y^3 * y^n
_______ = y^6
y
First we multiply the 2 y's together to get
y^n+3
____ = Y^6
Y
Then we will multiply y to both sides
y^n+3 = y^7
Get rid of y
n+3 = 7
n=4
