A° = 38, b°= 90, c° = 38
the square on the angle opposite to b shows that it is a right angle which means it’s 90°
Answer:
y= -x +2
Step-by-step explanation:
y-y1 = m(x-x1)
y - 0 = 1(x - (-2))
y = -x + 2)
y = x + 2.

I think the last you already have is right. I wasn’t very good at this but I try
Step-by-step explanation:
Answer:
h = √91 cm
Step-by-step explanation:
Apply pythagorean theorem, a² + b² ° c².
Where,
a = ½(6) = 3 cm
b = h
c = 10 cm
Plug in the values
3² + h² = 10²
9 + h² = 100
9 + h² - 9 = 100 - 9
h² = 91
h = √91 cm
