The measure of two complementary angles are represented by x+5 and 4x - 15 find the value of x

Answers

Answer 1
Answer:

Based on the calculations, the value of x will be equal to 20°

First and foremost, we should note that the total angles in a complementary angles equal to 90°.

In this case, we have to add the two angles that we are give and then equate them to 90°. This will be:

(x + 5°) + (4x - 15°) = 90°

x + 5° + 4x - 15° = 90°

Collect like terms

x + 4x = 90° - 5° + 15°

5x = 100°

x = 100°/5

x = 20°

Therefore, based on the calculations, the value of x is 20°

Answer 2
Answer: complementry angles sum up to 90.
so, (x+5)+(4x-15)=90
x+4x+5-15=90
5x-10=90
5x=90+10
x=100/5
x=20

What is the next number?
2, 7, 26, 101, 400, ?

Answers

It is 1595. Put it on excel so you can better have an overview how it is done. You need 5 columns, column A-E. On column A, put 1 to 5 in rows 1 to 5. On column C, put the answers: 2, 7, 26, 101 and 400. On column D, put number 3 in all 5 rows. Back on column B, insert =sum(C1-A1) on row 1 and copy till row 5. On column E, insert =sum(B1+C1*D1) on row 1 and copy till row 5 and you will get 1595 at the end.
7/2=3.5
26/7=3.7
101/26=3.9
400/101=4
400 x 4 or 4.1 = 1600 or 1640

Answer:

75 + 64 = 139

Step-by-step explanation:

The measure of the exterior angle is 139

Answer:

2= 139

Step-by-step explanation:

A triangle is 180 degrees.

64+75= 139

180-139=41

A line is also 180 degrees

180- 41= 139
