Find x
5x-17 = 3x + 1
5x -3x = 17 + 1
2x = 18
2x/2 = 18/2
X = 9
Find the measure of FG
mFG = 5x - 17
mFG = 5(9) - 17
mFG = 45-17
mFG = 28
Answer:
Given that,
In right triangle ABC, C is the right angle.
sin A=0.4
To find cos B,
we get the triangle as,
we know that,
Hypotenuse of the triangle is AB
For the angle A, opposite side is CB
For the angle B, adjacent side is CB
From the definition of sine and cosine we get,

Also,

Comparing both we get,

It is given that sinA=0.4
Hence we get, cosB=0.4
Answer is: 0.4
X + 3= 5
The answer to this equation is simply 2
to do this:
subtract 3 from both sides of the equation.
3 cancels out, and you are left with this
x=2
so, the answer is x=2
or 2
Hope this helped!
