$\angle D =\angle B\\\\
\angle B=\angle A+30\\
\angle A+ \angle B=180\\\\
\angle A+\angle A+30=180\\
2\angle A=150\\
\angle A=75\\\\
\angle B=75+30=105\\
\boxed{\angle D=105}

The sum of three numbers is 85. The second is 7 more than the first. The third is 2 more than four times the second. Find the nu

9966 [12]

Let x=the first number
Then x+7=second number
And 4(x+7)+2=third number (2 more than 4 times the second)
Now we are told that:
x+(x+7)+(4(x+7)+2)=85 get rid of parentheses
x+x+7+4x+28+2=85 simplify
6x+37=85 subtract 37 from each side
6x+37-37=85-37
6x=48
x=8---first number
x+7=8+7=15 second number
4(x+7)+2=4*15+2=62 third number

8+15+62=85
85=85

These two rectangles are similar which is a correct proportion for corresponding sides

hammer [34]

to make the proportion we make the ratio of the similar sides

For example

4/8 = 12/x

or we can write it as 4/12 = 8/x

or 12/x = 4/8

So last option is correct
