so you can write the sum of angles =90°
3x+4x+6 =90
7x=84 x=12
so answer 3*12 =36°
and 4*12+6 =54°

Complimentary angles have a sum of 90 degrees, so:
3x +4x+6 =90
7x+6 =90
7x = 84
x = 12
3x = 3*12= 36 degrees
4x+6 = 48+6 = 54 degrees

by definition, the SUM of complimentary angles add up to 90 degrees, therefore:
(3x) + (4x + 6) = 90 ... now solve for x
3x + 4x + 6 = 90
7x +6 = 90
7x = 84
x = 12
substitute x back to find the measure of each angle:
first angle ... 3x ... 3(12) ... 36 degrees
second angle ... 4x + 6 ... 4(12) +6 ... 48 +6 ... 54 degrees
check your answer, 36 + 54 = 90 ... so they are correct

Easy.
Complimentary angles add up to 90 degrees.
So, 3x + 4x+ 6 = 90
=> 7x + 6 =90
=> 7x = 90 - 6
=> 7x = 84
=> x = 12
Therefore the angles are 3x = 3*12 = 36
and 4x + 6 = 4*12 + 6 = 54
36 and 54 degrees.
Enjoy.

Complimentary means that their sum is 90 degrees. This gives you:
3x+4x+6=90
Solve for x and you get x=12
now plug in for x and you get
3x = 36 degrees
and
4x+6= 54
To check, add the two numbers and make sure they equal 90

3x+4x+6=90
7x+6=90
7x=84
x=12
So the angles are 36 degrees and 54 degrees

it is actual fairly ordinary. Geometry tells us that the sum of the angles of any triangle is one hundred eighty. so we are in a position to assert that one hundred eighty = 2x + 4x+7 + 3x+2. as quickly as we integrate like words we get one hundred eighty = 9x + 9. From right here we've a pair distinctive selections. we are in a position to subtract 9 from the two factors then divide by 9 to discover x or we are in a position to divide by 9 now and subtract over one million to discover x. shall we do the branch final because of the fact we won't continuously do it at this point. Subtract 9 from the two factors provides us 171 = 9x. Now only divide by 9 and we've 19 = x TA DA! Math be completed!

we know that complimentary angles add up 90 degrees!
therefore 3x+4x+6=90
now let's solve for x
7x=84
x=12
substitute x for 12
3x=36
4x+6=54
now let's add up the the two which should add up to 90
54+36
90.
hope that answers your question!!
am out!
