Answer:
18
Step-by-step explanation:
multiply then add a all together
What do you mean by "reasoning" if you mean by doubling you just keep adding till you get the sum.
Answer:
it's D
Step-by-step explanation:
y= .05x+20
x=50
y=.05(50)+20
2.5+20
y=22.5
y=.25x+10
x=50
y=.25(50)+10
12.5+10
y=22.5
The measure of <TRS and angle d are 70 and 43degrees respectively
<h3>Triangles and angle</h3>
The given triangles are isosceles triangles since they have two equal sides.
14) From he triangle RST
<TRS + 90 + 20 = 180
<TRS + 110. = 180
Subtract 110 from both sides
<TRS = 180 -110
<TRS = 70 degrees
15) For this triangle;
d = 86/2
d = 43 degrees
Hence the measure of <TRS and angle d are 70 and 43degrees respectively
