PLSS HELP WILL MARK BRAINLIEST!

Mathematics
1 answer:
ANEK [815]3 years ago
6 0

Answer:

y = 5

Step-by-step explanation:

The triangle is an isosceles triangle, which means that it has two equal sides and two equal angles.

Therefore, angles B and C are both equal to 75°.

A triangle measures 180°.

75 + 75 + x = 180

150 + x = 180

x = 30°

Angle A has to equal 30°.

(4y + 10)° = 30

4y + 10 - 10 = 30 - 10

4y = 20

y = 5

Hope that helps.

then

∡AOY+∡YOZ+∡ZOB=180°

so

3x+x+x=180-----> 5x=180--------> x=180/5--------> x=36°

the answer is

x=36°

Explain why multiplying a fraction by 5/6 results in a value that is less than the original fraction
Ivahew [28]

Answer:

Step-by-step explanation:

(5/6) itself is less than 1 (but greater than 0).  Thus, anything multiplied by (5/6) will result in a smaller-by-magnitude quantity.

For example, (5/6)(3/4) is LESS than 3/4 because 5/6 is greater than zero but less than 1.

Last summer, Betty earned $4200 by painting houses. She invested
Musya8 [376]

x*(1.035) + (4,200-x)*(1.045) = 4,374.00

1.035x + 4,389.00 -1.045x = 4,374.00

15.00  = .01x

x = 1,500  so x (1,500) invested at 3.5% and  

(4,200 - 1,500) (or 2,700) invested at 4.5%
