Answer:
x = 13
39° and 51°
Step-by-step explanation:
Angles in a triangle add up to 180 degrees.
This is a right angle triangle, so one side has a size of 90 degrees.
3x + 4x - 1 + 90 = 180
7x + 89 = 180
7x = 91
x = 91/7
x = 13
Put x as 13 to work out the size of the angles.
3(13) = 39
4(13) - 1
52 - 1 = 51
Answer:
9x = 1-1 is q r x= 2x2 + 2 is 4
Distribute the “-3” to both n&-3 —> -3n+9 then your left with -5 and subtract 9-5
-3n+4
Hope this helps:)
It will be 93 because it 92 but you have to round up with deimal number
