Answer:
C. 52°
Step-by-step explanation:
In ∆CAB, m<A = right angle = 90°
m<B = 38°
m<C + m<A + m<B = 180° (sum of ∆)
m<C + 90° + 38° = 180° (substitution)
m<C + 128 = 180
m<C = 180 - 128 (subtraction property of equality)
m<C = 52°
9y - 5x = 20
or, (9y - 5x) / 20 = 1
or, 9/20 y - 1/4 x = 1
compare with x/a + y/b = 1
you'll get
x intercept (a) = -4
y intercept (b) = 20/9
Answer:
2x(x + 3)
Step-by-step explanation:
Given
2x² + 6x ← factor out the common factor 2x from each term
= 2x(x + 3)
H is 3 . I used the formula for a cone
