Answer:
13 cm
Step-by-step explanation:
Use Pythagora's theorem to solve for the hypotenuse of the triangle:
Where a and b are the two shorter legs, and c is the hypotenuse.
Replace the values in and solve for c:
-7 because when it’s +(-) it’s always the same as the outside sign
-4 same thing explained above
-4

So the first two questions are asking for points of intercept. a is asking where the function crosses the x, in this case it is where y=0. So your x intercept is at x= 1,5. Then to find the y intercept it is where x=0, so just substitute 0 for x. Then you get your y intercept as y=5. Because your coefficient for the quadratic function is positive your function has a minimum since it opens upward. I’m not sure what is means by C coordinate, but your vertex is at (3,-4) and lime of symmetry is at x=3.
X intercepts: (1,0) and (5,0)
Y intercept: (0,5)
Angle E=130degrees because those two are congruent. Therefore if you 180-130 you'll get the other angle in the triangle with 70degrees and y. 180-130=50degrees. Then add 50 and 70. 50+70=120degrees. A triangle is supposed to have 180 degrees inside.
180-120=60degrees.
Therefore y=60degrees
The answer is.. 23 and 16
