Please help me and can you write an explanation too please.

Step-by-step explanation:

Hello There!

Once again the angles shown are supplementary angles meaning that the sum of the measure is equal to 180

so we use this equation to solve for x

180 = x + 4x + 35

step 1 combine like terms

x + 4x = 5x

now we have 180=5x+35

step 2 subtract 35 from each side

180 - 35 = 145

35 -35 cancels out

now we have 145 = 5x

step 3 divide each side by 5

5x/5=x

145/5=29

we're left with x = 29
