I'm too late but here ya go anyway :)
x = 180 - (31 + 40) is the answer.
T=PV/Rn you just divide both sides by Rn
Answer:
the answer should be 12
Step-by-step explanation:
Answer:
a.
b.

Step-by-step explanation:
a. We know that angles in a triangle add up to 180°.
-The right angle triangle in the right triangle has a measure of 90°.
We can therefore equate our angles to 180° and solve for x;

Hence, the angle measure is x=10°
b. Having calculated the value of x from a above as x=10°, we can substitute to find the measures of the two acute angles:

Since, the m∠K is a right angle, it measures 90°
