Answer:

The answer to your question is ∠3 = 63°

Step-by-step explanation:

Data

∠2 = 117°

∠3 = x

Process

1.- Angles 2 and 3 are supplementary which means that their addition gives 180°.

So,

                ∠2 + ∠3 = 180

Substitution

                 117° + ∠3 = 180°

Solve for ∠3

                           ∠3 = 180° - 117°

Simplification and result

                            ∠3 = 63°

hodyreva [135]

Since we have given that

Cost of their most popular meals are as follows:

\$7,\$8,\$8,\$12,\$13,\$15,\$17,\$18,\ and\ \$20

This helicopter has a rotor that moves at a rate of 600 spins per minute while flying. Which statement is supported by this info
jeka57 [31]

Answer: d. The helicopter rotor will spin 36,000 times in 1 hour

Step-by-step explanation:

Option A is wrong because in 40 minutes the rotor will spin:

= 40 * 600

= 24,000 times

Option B is wrong because we cannot know the number of times the rotor will spin before being lifted off of the ground with the details given.

Option C is wrong because in 3 hours the rotor will spin:

= 600 * 3 * 60 minutes

= 108,000 times

Option D is correct because in 1 hour the rotor will spin:

= 600 * 1 * 60 mins

= 36,000 times
