You have to find the LCM (least common multiple) of both numbers.
3: 3, 6, 9, 12, 15
5: 5, 10, 15

If triangles PQR and STU are similar then PQ corresponds to ST and PR corresponds to SU. Therefore, PQ/ST=PR/SU
Considering that, PQ= 7-x, ST= 13-x, PR= x²+5 and SU= x² +20
therefore, (7-x)/(13-x)= (x²+5)/(x²+20)
cross multiplying,
7x² +140-x³+20x =13x²+65-x³-5x
combining the like terms,
6x² +15x -75=0
solving for x,
x = 5/2 or -5
When a quadrilateral is inscribed in a circle, the opposite angles are supplementary.
x + 2 + 3x + 6 = 180
4x + 8 = 180
4x = 172
x = 43
Now solve for A
3(43) + 6 = A
129 + 6 = A
135 = A
The measure of angle A is 135 degrees.
Hope this helps =)
9.) Answer: B. f(x) = 4 - x
Explanation/Proof:
If we substitute, the answers are correct.
f(x) = 4 - (1)
f(x) = 3 ✅
f(x) = 4 - (2)
f(x) = 2 ✅
And so on and so forth.
