If ∠G is supplementary to ∠H and the measure of ∠G is 65° what is the measure of ∠H?

Elina [12.6K]

Solution:

Given:

∠G = 65°

Supplementary angles are a pair of angles that sum up to 180°.

It should be noted:

If ∠G and ∠H are a pair of supplementary angles, they both sum up to 180°.

Equation formed: ∠G + ∠H = 180

Substitute the values into the equation.

∠G + ∠H = 180
=> 65 + ∠H = 180

Subtract 65 both sides.

=> 65 - 65 + ∠H = 180 - 65
=> ∠H = 180 - 65 = 115°

Please i need the step-by-step solution please thank you

Sergio [31]

Answer:

Question 6: -8

Question 7: C

Step-by-step explanation:

Question 6:

The reason question 6 is -8 is because of the distance in between each number, e.g -7 and -15. This is not to be confused with + 8 each time that would make the sequence 9, 18, 27.

Question 7:

The way we solve this question is using the nth term rule, whatever is before the n is the times tables we follow. So if it is 2n the sequence would be 2, 4, 6, 8 etc. However when we add something like the -2 we do the 2 times tables but this time we -2 for each one. Example: 2 - 2 = 0 so the first number of the sequence is 0, Example 2: 4-2 = 2 so the second number of the sequence is 2.
