Answer:
1: 36° 2: 122° 3: 122° 4: 38°
Step-by-step explanation:
First start out by getting 2 and 3. so 58+angle 3 has to sum to 180° since they are supplementary and are a straight line. So 180-58=122. Angle 2 is the same since theyre vertical. then since a triangle has 180° total, you subtract from 180 to find the final angle measurement.
Answer:
x = 10, y = 5
Step-by-step explanation:
Substitute the second equation into the x value of the first equation.
-4x + 11y = 15
-4(2y) + 11y = 15
-8y + 11y = 15
3y = 15
y = 5
Now substitute the y value into an original equation.
x = 2y
x = 2(5)
x = 10
35-19 equals 16
16 is the answer
