Answer:

x=8

Step-by-step explanation:

this is an equilateral triangle, which means all sides are equal

if all the sides are equal, all the angles are equal

the three angles are all equal to 60 degrees (180/3 = 60)

7x+4 = 60

subtract 4 from each side

7x = 56

divide by 7 on each side

x = 8

Answer:

x=8

Step-by-step explanation:

This triangle is an equilateral one, and so all three angles are the same; their measure is 60 degrees each.  Thus, 7x + 4 = 60, or 7x = 56.

x comes out to 8.

OLEGan [10]

Answer:

Step-by-step explanation:

Would an experience downhill skier want the slope of the hill to be 1/10 or 9/10?  Why?<br><br>​
kolezko [41]

Answer:

9/10

Step-by-step explanation:

step 1

Compare the slopes

1/10=0.10

9/10=0.9

0.9 > 0.10

therefore

An experienced skier would like the 9/10 hill slope because it is steeper, while the 1/10 is a softer slope.
