Answer:

SUM OF ALL ANGLES ÓF A TRIANGLE=180

THEREFORE,

4X+7X-2+5X-10=180

16X-12=180

16X=192

X=12

THEREFORE,

<A=4X=4*12=48

<B=7X-2=7*12-2=84-2=82

<C=5X-10=5*12-10=60-10=50

Answer:

...

Step-by-step explanation:

7x - 2 +5x - 10 +4x = 180

16x - 12 = 180

16x = 168

x = 10.5

now plug it in

7(10.5) - 2 = 71.5°

4(10.5) = 42°

5(10.5) -10 = 42.5°

Fredericka can make 65% of her shots from the free-throw line. if she shoots 75 times, how many shots can she expect to go in?

exis [7]

All we need to do is find 65% of 75
we need to know that 65% = 0.65
and we multiply 0.65 and 75
soooo
75 x 0.65 = 48.75
so she sould expect to make about 48 shots into the hoop
hope this helps:)
