Answer:
step 1: x+50+4x=90
the angle of a right-angled triangle is 90 degrees, therefore if we add everything together ,we could work out what x is.
step 2: x+50+4x=90
x+4x=50
5x=50
x=10
then you solve the equation, x is 10
Answer:4x+12
Step-by-step explanation:
4 times x is 4x and 4 times 3 is 12

Step-by-step explanation:
Step-by-step explanation:
3x+7y-12=0
3x+7y=12
3x=12-7y
x=12-7y/3
Measure of angle 1.
Angle ALS consists of angle 1 and 2. When you take the angle 2 away, subtract it, it ends with angle one.
