I NEED A STEP BY STEP BY EXPLANATION PLS ASAP !!
answers :
1) 130 degrees
2) 56 degrees
3) 5
4) 10
5) 24 degrees
6) 91 degrees

1:

Angles on a straight line add to 180degrees

2:

Anglea o na straight line add to 180degrees

Step-by-step explanation:

Don't know about the rest

Step-by-step explanation:

1) In a triangle, there is 180 degrees. That means that the last angle in the measure is going to be 50. Now, DCH and ECD are supplementary angles. 180-50=130 degrees

2)DEC=180-76 (because they are supplementary angles) 180-76=104 degrees

The measures in a triangle add up to 180 degrees. So, 104+x+20=180x=56 degrees

3)RTS=180-16x-5-50. You should basically do the same thing here as the last couple of questions.

4)180-96=84. This is the measure of the other angle inside the triangle. Now, form the equation: x+10+8x-4+84=180 x=10

5)3x-6+69+180-8x+13=180 x=24

6)7x-4+39+180-12x-5 x=91

Basically just make an equation for all of these problems. Mainly used supplementary angles to form equations.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hope i
