Answer:
Step-by-step explanation:
x + 3x + 4x + 70° + 90° = 360° ( being complete turn )
8x + 160° = 360°
8x = 360° - 160°
8x = 200°
x = 25°
3x = 3 * 25°= 75°
4x = 4 * 25° = 100°
Answer:
x=20
3x= 3(20)=60
4x= 4(20)=80
Step-by-step explanation:
The angles CD is 90 degrees because the small square indicates
it. Angles AD are a straight angle, therefore all the other angles within A to D, must equal 180 degree. (straight line/angle=180 degrees).
so AB + 70+ 90= 180 degrees
AB= 180 -70-90
AB=20
x=20
3x= 3(20)=60
4x= 4(20)=80

3*|2-7| = 3*|-5|......absolute values are positive even when they say negative.
so 3*| -5 | = 3 * 5 = 15
