<span>y=2x+7
y=9x+8
From (1),
x= (y-7)/2
Substituting value of x in eqn (2) we get,
y= 9.(y-7)/2 + 8</span>
Answer:
here's the answer to your question
4x+40=180
4x=180-40
4x=140
x=35
angle A= 35°
angle B= 35(4)+40= 145°
Answer:
a. -21 b. 14
Step-by-step explanation:
For a, -3x4=-12, and then -12-9=-21. For b, -1/3x-3=1, and then 1+13=14. Hope it helps!
<u>Given</u>:
Given that HIJ is a right triangle.
The measure of ∠J is 90°, JI = 5, IH = 13, and HJ = 12.
We need to determine the value of sine of ∠H
<u>Value of sine ∠H:</u>
The value of sine ∠H can be determined by using the trigonometric ratios.
Thus, we have;

Substituting the values, we get;

Dividing, we get;

Taking
on both sides, we have;


Rounding off to the nearest hundredth, we get;

Thus, the measure of ∠H is 22.62°
