Answer:
2x+27=7
2x=-20
x=-10
Step-by-step explanation:
substitute 3 in for all y's and multiply.
20 degrees. The pics a little blurry, but it should be that
Answer:
4) 8+2i
Step-by-step explanation:
When you expand you get 3+4i+5-2i
when you add the like terms you get 8+2i
Since the sum of both angles <ORQ and <SRQ is 180 degrees, hence the two angles that are supplementary are <ORQ and <SRQ
<h3>What are supplementary angles</h3>
Supplementary angles are angles that sums up to 180 degrees..
Since the line SR bisects the line OQ, hence the angle <ORQ and <SRQ are equal and equal to 90 degrees each,
Since the sum of both angles <ORQ and <SRQ is 180 degrees, hence the two angles that are supplementary are <ORQ and <SRQ
