Answer:
x = 60°
Step-by-step explanation:
the triangle has 3 congruent sides and is therefore equilateral with 3 congruent angles, each of 60°
x and the angle on the right vertex are alternate angles and are congruent, so
x = 60°
Answer:
y intercept
Step-by-step explanation:
At first I didn't think there was enough information, but there is. In general terms, for any polynomial which is also a function, making x = 0 gives the point where (0,b) = the y intercept.
For example
using f(x) = x^2 + 4x + 6 when x = 0 the result left is f(0) = 6 so the y intercept is (0,6)
If you have x^2 + 6x the y intercept is (0,0)
Answer: ×/2 + 9 =
Step-by-step explanation: when a sentence needs to be visualized it is best to strat from the outside.
So if nine more than blah blah equals 21,
... +9 = 21
Find comon factors
300m^2=2*2*3*5*5*m*m
120m=2*2*2*3*5*m
180=2*2*3*3*5
GCF=2*2*3*5=60
factor out 60
60(5m²+2m+3)
answer is last one
Answer:
Step-by-step explanation:
This are similar triangle
<ABD = <ACE
CE/BD = AE/AD
33/11 = 15/AD
Let AD be x
33/11 = 15/x
Cross multiply
33x = 11×15
33x = 165
x = 165/33
x = 5
AE = AD + DE
AE = 15, AD = x = 5 and DE = y
: 15 = 5 + y
y = 15 - 5
y = 10
BD/CE = AB/AC
11/33 = 9/(x+9)
Cross multiply
11(x+9) = 9(33)
11x + 99 = 297
11x = 297 - 99
11x = 198
x = 198/11
x = 18
