If the triangles are similar, then the angles are all congruent.
Therefore, we can start by setting the two middle angles equal to each other.
4x + 7 = 5x - 10
7 = x - 10
x = 17
Middle angle = 75
Now that we know our x-value, we can simply plug in x for our other two expressions.
3 * 17 = 51
4(17) - 14 = 54
We can check to make sure that our angle measures are correct by adding them all up and making sure they equal 180.
54 + 51 + 75 = 180
180 = 180
Hope this helps!! :)
Answer:
0.0098
Step-by-step explanation:
Probability of being pregnant:100/1000
=1/10.
98% chance:=98/100 ×1/10
=98/1000
Therefore the probability that she really is pregnant is: 0.098
<span>×^2+5×-24=0
(x+8)(x-3) = 0
x+8 = 0, x = -8
x - 3 = 0, x = 3
answer: </span>x = -8 and x =3
Answer:
angles are 40 and 50
Step-by-step explanation:
let angles be 4x , 5x
4x + 5x = 90
x= 90 / 9
x= 10
angles are 4x , 5x
therefore angles are 40 , 50
