Answer:
100 degrees
Step-by-step explanation:
Since triangle ABC is similar to triangle DEF, their angles are basically the same.
All angles of a triangle have to add up to 180.
We are already given two angles: 30 and 50
Add them together: 30 + 50 = 80
Now we subtract the number from 180
180 - 80 = 100
The remaining angle has to be 100 degrees
Answer:
Square
Solve for area
A=225
a Side
15
Step-by-step explanation:
(X-10)(X-10)
You need to first multiply out the brackets. So, first times X by X, which makes x^2 . Then do -10 x -10 which makes 100. You then need to multiply the X within the first bracket with the minus 10 in the second bracket which makes -10x. Do the same but with the -10 from the first bracket and the X from the second which again makes -10x. So altogether you have x^2-10x-10x+100. This can be simplified down to x^2-20x+100. You then do the same thing for the second question :)
The present value of the loan will be = R36,250
<h3>Calculation of the present value</h3>
The principal capital (P) = R25 000
Interest rate for the payment (R)= 7.5%
Time for the payment (T)= 6 years
Therefore simple interest = P×T×R/100
= 25,000×6×7.5/100
= 250×6×7.5
= R11,250
The present value of the loan will be;
= 25,000 + 11,250
= R36,250

P = √ab
p² = ab
p²/b = a
a = p²/b
