Answer:
3(4+3x)
Step-by-step explanation:
See Image below.
All quadrilaterals have a total of 360 degrees so...
90+76=163
163+111=274
360-274=86
The measurement for the 4th angle would be 86 degrees
Answer:
420
Step-by-step explanation:
15%= 0.15
2800*0.15= 420
Answer:
Alternate Interior Angles
Step-by-step explanation:
Angles can be corresponding; alternate or same side; or interior or exterior. The angles 2 and 8 are on opposite sides of the transversal; this means that they must be alternate angles. Additionally, they are both within the parallel lines, so they are interior. Alternate interior angles are always congruent. Therefore, their measurements must be equal.
