Vocaloid:
All the side lengths are different, choose the appropriate term based on this fact
johnnn:
isosceles?
Vocaloid:
Nah that would mean two sides are equal Scalene = all sides different
Vocaloid:
All the angles are diff so which would this be?
johnnn:
Scalene?
Vocaloid:
Yes
johnnn:
wait im confused...Scalene isnt one of the answers
Vocaloid:
Oh sorry Since we have an angle greater than 90 it’s obtuse
Vocaloid:
Use the small triangle to solve for y first Y + 90 + 29 = 180
johnnn:
61?
Vocaloid:
Good then we Use the big triangle to solve for x (X+y) + 90 + 17 = 180
johnnn:
so 61 is the final answer?
Vocaloid:
No Like I said you need to solve for x
johnnn:
12
Vocaloid:
Good that’s your solution
Vocaloid:
Remember your centroid proportions BW is (2/3) BE
johnnn:
9?
Vocaloid:
2/3 of 9 is not 9
johnnn:
ohh so 6
Vocaloid:
Good
Vocaloid:
The incentrr is made by angle bisectors So angle B is 2 times 32, since 32 is only half the angle Angle A is 2 times 34 using the same logic Using the fact that all angles in a triangle sum to 180 find angle C
johnnn:
57
Vocaloid:
Check your calculations again
Vocaloid:
Remember, 32 is HALF of angle B and 34 is HALF of angle A
johnnn:
24
johnnn:
wait no
johnnn:
ohh its 114 lol
Vocaloid:
Angle A = 2*34 = 68 Angle B = 2*32 = 64 Angle C = 180 - angle B - angle A =?
johnnn:
48
Vocaloid:
Good, now it only wants JCA which is half of angle C So 48/2 = 24 = your solution
Vocaloid:
For this one the left triangle and the right triangle are congruent via SAS So see what you can get from that
johnnn:
6.74
Vocaloid:
Hint: the side lengths on the left and right triangle must be equal
johnnn:
10.8
Vocaloid:
Notice how the right triangle has leg 6 hypotenuse 9 The left triangle must also have leg 6 hypotenuse 9
johnnn:
oh duhh the answer is 9 lol
Vocaloid:
Yes
Vocaloid:
This triangle is isosceles so the bottom two angles must be equal Therefore 2x + 52 = 180
johnnn:
is the answer 38?
Vocaloid:
Check your calculations again
johnnn:
64
Vocaloid:
Good that’s it
Vocaloid:
All the sides are equal so all the angles will be equal as well. So if there equal angles add up to 180 what’s the measure of each angle?
Vocaloid:
There are 180 degrees Divide this amongst three angles 180/3 =?
johnnn:
60
Vocaloid:
Good.
