Pls help I’m rlly confused. The question says “find the value of x using complementary angels” ty <3
Arturiano [62]

Answer:

x=83. please look below for explanation. if anything isn't clear, please ask

Step-by-step explanation:

so complementary means adding up to 90 degrees in math. in this particular equation, you have to make sure that both (x-18) and 25 add up to 90.

if that other side is 25 degrees, the other side must be 65 because 90-25=65.

so now you have to set those equal to each other like this:

65 = (x-18)    now just solve for x

add the 18 to the other side. the -18 and +18 cancel.

x=83

so to test and to see if that is right, we can do

83-18 = 65

does 65+25 equal 90? yes

therefore, x=83

Solve for x. Show each step of the solution. 4.5(8−)+36=102−2.5(3+24) i need to show my work dont just give me the answer
elena-s [515]
4.5 * (8-) + 36 = 102 - 2.5 * 27
4.5 * 8 - 36 = 102 - 2.5 * 27
36 - 36 = 102 - 2.5 * 27
36 - 36 = 102 - 67.5
36 - 36 = 34.5
Since we know 36 - 36 doesn't equal 34.5 its not true so there is NO ANSWER.
