So here is how we are going to get the measure of angle 2.
Since given that angle COE measures 55°, we will equate <span>m∠2 = 2x and m∠3 = x+10 with 55. So, 55 = 2x + x + 10
55 = 3x + 10
55-10 = 3x
45 = 3x << divide both sides by 3 and the result is
15 = x
So now that we know x, we can now solve for angle 2.
</span>m∠2 = 2x
m∠2 = 2(15)
m∠2 = 30<span>°
I hope that this is the answer that you are looking for. </span>
Answer:
u=-5
Step-by-step explanation:
Slope is y(2)-y(1)/x(2)-x(1). So, your equation is u-10/-2-1. -2-1=-3, so the top number has to be negative to get a positive and has to be 5 times more than three. So, the numerator for the slope would be -15, because -15/-3=5. So, u is equal to -15-10. Therefore u equals -5.

Given:
The figure of a right triangle ABC.
To find:
The trigonometric ratios 
.
Solution:
Using Pythagoras theorem,
Taking square root on both sides.
So, measure of BC is 8 units.
Now,
Similarly,
And,
Therefore, the required trigonometric ration are 
.
Y intercept:
y = (-3x + 5)/2
x intercept;
x = (-2y + 5)/3
hope this helps
