What are the measures of the two angles in the figure below?

You can see that the two angles sum up to 90°. So, you have the following equation:
[tex] (4x+2)+(3x+4) = 90 \iff 7x + 6 = 90 \iff 7x = 84 \iff x = \dfrac{94}{7} \iff x = 12 [/tex]
So, angle above measures
[tex] 4x+2 = 4\cdot 12+2 = 48+2 = 50 [/tex]
And the angle below measures
[tex] 3x+4 = 3\cdot 12+4 = 36+4 = 40 [/tex]
These 2 angles add up to 90 degrees, so
4x + 2 + 3x + 4 = 90
7x = 90 - 6 = 84
x = 12
So the 2 angles are 4*12 + 2 = 50 and 3(12) + 4 = 40
Answer 50 degrees and 40 degrees (the top one is 50 degrees)
