What is the measure of an angle that is nine times it’s complement

Mathematics
1 answer:
Ierofanga [76]3 years ago
8 0

Answer:

9

Step-by-step explanation:

Assume that the measure of the angle is x

That would mean that the compliment of that angle would be 9x

Two angles are complementary when their sum equals 90

That means x + 9x equals 90.

We can combine x and 9x into 10x, leaving us with 10x=90

Divide both sides by 10

x=9

Ruden bought 6 new books for his collection, increasing his collection by 12%. How many books did he have before his purchase?
forsale [732]

Answer:

he had 44 books before he bought those 6

Step-by-step explanation:

If you multiply 6 times 2 it is 12, which means if you take away 12 from 100 that is 88. if you divided 88 by 2 (the same thing you did to the 6 to make it 12%) that would be 44.

Please help, Will give brainliest
Talja [164]

Answer:

First since 2 of the options ask for the width of BM lets solve for it using the Pythagorean theorem for both sides of point L:

a² + b² = c²

30² + b² = 50²

b² = 50² - 30²

b² = 1600

b = 40    Line BL = 40 ft

Since the ladder is 50 feet it is the same length on the other side as well

a² + b² = c²

40² + b² = 50²

b² = 50² - 40²

b² = 900

b = 30        line LM is 30 ft

SO line lm + line bl = 30 + 40 = 70 ft

A is true because ^

B isn't true because as we solved for earlier, BL is 40

C is true because line LM is in fact 30 ft as we solved for

D is not true because as we said earlier BM is 70

E is true because the same ladder was used on both sides of the street
