This is an equilateral triangle because all the sides are the same length shown by the tic marks. This means that the angles are also all congruent. so...
S=T=R this also means that all angles are 60 degrees because all triangles angles added together are 180 degrees. so that means that you put all of the equations equal to 60. but if u are looking for x only here is the answer
7x+4=60
7x=56
x=8
Answer:
x+5=5
Step-by-step explanation:
This is an equation where you are actually solving it. The others are expressions.
Hey there!
Since there are 3 friends running an equal amount of this relay race, each will run 1/3 of the relay.
This is because 3 thirds make a whole, and each third is equal to the others, so if you add each distance ran by each of the friends, or simply multiply each portion by 3, you'd get 10 miles.
If you're also looking for how long each friend runs, which I know isn't in the question but I'll add it anyways, it is 3 1/3 miles. This can be found by dividing 10 into 3 equal parts.
Hope this helps!
