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:
100/90*18= 20%
Step-by-step explanation:
The value of y when x is equal to zero will be 330.
<h3>What is a system of equations?</h3>
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
The given function is;
y = 330 + 25x
We have to find the value of y when x is equal to zero.
So,
Put x = 0
y = 330 + 25x
y = 330 + 25(0)
y = 330
Hence, the value of y when x is equal to zero will be 330.

Answer:
65.837 km/h to nearest thousandth
Step-by-step explanation:
60 ft/s = 60 * 3600
= 216,000 ft /h
1 foot = 30.48 cms so
216,000 ft/h = 216,000 * 30.48
= 6583680 cms / h
= 6583680 / 100,000
= 65.837 km/h to nearest thousandth
