Answer:
x = 61
Step-by-step explanation:
Left hand triangle containing 1 angle of 74
Label the other angle opposite the marked side also as 74
Find the third angle. Call it y.
y + 74 + 74 = 180           Combine like terms
y + 148 = 180                 Subtract 148 from both sides.
y = 180 - 148
y = 32
=============
Now work with the triangle on the right.
label the angle making up the right angle = z
32 + z = 90                             These two angles are complementary = 90
32 - 32 + z = 90 - 32              Subtract 32 from both sides
z = 58                                      Use 58 wherever you see z
x + x + z = 180                         Substitute
2x + 58 = 180                          Subtract 58 from both sides
2x = 122                                  Divide by 2
x = 61
