you are making a picture frame in your shop class. two peices of wood are cut to form complementary angles so they fit fit toget
Andrews [41]

Two angles are complementary when their sum is equal to 90°.

So, ( 2x + 39 ) + ( 7x - 21 ) = 90°

9x + 18° = 90°

x = 8°

Putting value of x in the angles given :

( 2x + 39 )° = 2(8°) + 39° = 55°.

( 7x - 21 )° = 7(8°) - 21° = 35°.

Therefore, the angles are 55° and 35°.

Hence, this is the required solution.

What is the fourth root of -16?
Zarrin [17]

Answer:

The answer to your question is 2i

Step-by-step explanation:

                                             \sqrt[4]{-16}

- Get the prime factors of -16

                                                  - 16   2

                                                   -  8  2

                                                   -  4  2

                                                   -  2  2

                                                       1

                                   16 = 2⁴

- Express the -16 as a power

                          \sqrt[4]{-2^{4}}  or   \sqrt[4]{2^{4}i^{2}}

Remember that -1 = i²

- Get the fourth root of -16

                                         2i
