I don't really get what you are asking for. Can you clarify it?
Hello,
Vertex=(-2,5)
x=0==>y=-3(0+2)²+5=-7
Answer:
6.68, 13.37, 14.95
Step-by-step explanation:
One of the legs is twice as long as the other.
b = 2a
The perimeter is 35.
35 = a + b + c
The triangle is a right triangle.
c² = a² + b²
Three equations, three variables. Start by plugging the first equation into the second and solving for c.
35 = a + 2a + c
c = 35 − 3a
Now plug this and the first equation into the Pythagorean theorem:
(35 − 3a)² = a² + (2a)²
1225 − 210a + 9a² = a² + 4a²
1225 − 210a + 4a² = 0
Solve with quadratic formula:
a = [ -(-210) ± √((-210)² − 4(4)(1225)) ] / 2(4)
a = (210 ± √24500) / 8
a ≈ 6.68 or 45.82
Since the perimeter is 35, a = 6.68. Therefore, the other sides are:
b ≈ 13.37
c ≈ 14.95

Answer:
40°
Step-by-step explanation:
The similarity statement tells you that angles W and P have the same measure. The sum of angles in the triangle is 180°, so we have ...
∠R +∠W +∠T = 180°
85° +55° +∠T = 180°
∠T = 180° -140°
∠T = 40°
I agree. Some people's questions keep getting deleted. Thanks you for bringing this up. Hopefully someone can contact the administrator.
