Answer:

x=4

Step-by-step explanation:

21x+6+90=180

First, we need to subtract the numbers.

21x=180-90-6

21x=84

Now, we need to find the value for 1x, so divide the whole equation by 21

84/21

21/21

x=4

Hope this helps!

Help me with the answer please
PSYCHO15rus [73]
Y=10 because on the left X has to equal 30 in order for the angle to be 90 degrees. After that you take the X which is 30 and put it in the equation (2X+3Y) Now the line is a line which means that the angle containing (2X+3Y) must equal 90 like this (2X+3Y)=90 So plug in X [2(30)+3Y]=90 60+3Y=90 subtract the 60 and you get 3Y=30 divide 30 by 3 and you get Y=10 Hope this helped
