Phytagorean Theorem i think
Answer:AGC and DGH are opposite angles.
Step-by-step explanation:
So, Y+10=3x-40
Y-3x=-50-(1)
3x-40=2x
3x-2x=40
x=40
Y-3x40=-50
y-120=-50
y=-50+120
y=70
Hence, the answer is A 70°

Answer:
Sum of the first 15 terms = -405
Step-by-step explanation:
a + 3d = -15 (1)
a + 8d = -30 (2)
Where,
a = first term
d = common difference
n = number of terms
Subtract (1) from (1)
8d - 3d = -30 - (-15)
5d = -30 + 15
5d = -15
d = -15/5
= -3
d = -3
Substitute d = -3 into (1)
a + 3d = -15
a + 3(-3) = -15
a - 9 = -15
a = -15 + 9
a = -6
Sum of the first 15 terms
S = n/2[2a + (n − 1) × d]
= 15/2 {2×-6 + (15-1)-3}
= 7.5{-12 + (14)-3}
= 7.5{ -12 - 42}
= 7.5{-54}
= -405
Sum of the first 15 terms = -405
3p < 12
p < 4
and
-3p < 12
p > -4
answer
-4< p < 4
It's C. third one
