∠A and \angle B∠B are complementary angles. If m\angle A=(8x+27)^{\circ}∠A=(8x+27)

Mathematics

Amanda [17]4 years ago

Answer:

∠ B = 15°

Step-by-step explanation:

Complementary angles sum to 90° , that is

∠ A + ∠ B = 90 , substitute values

8x + 27 + 6x - 21 = 90

14x + 6 = 90 ( subtract 6 from both sides )

14x = 84 ( divide both sides by 14 )

x = 6

Thus

∠ B = 6x - 21 = 6(6) - 21 = 36 - 21 = 15°

Are triangles PRU and STQ congruent?
san4es73 [151]

No, triangles PRU and STQ are not congruent. Even though their angles are the same, different triangles can be constructed out of triangles with the same angles. Looking at the picture, one can also see the difference in size between the two triangles.
