~Divide 2 to both sides
a = 10
Best of Luck!
Answer:
BCD = 60
ABD - 90
Step-by-step explanation:
BCD)
BC and CD are the same length on in the circle, they are the radius. Therefor, all angles will be the same at 60
ABD)
All angles together are 180
You know 2 Angles, A at 30 and D at 60
180 - 30 - 60 = Angle B
90 = Angle B
Answer:
−12/17
Step-by-step explanation:
This is the answer because:
1) First, convert 2 5/6 to an improper fraction
2 5/6 = 17/6
2) Next divide -2/1 and 17/6
3) The reciprocal of 17/6 is 6/17
4) -2/1 ÷6/17 is -12/17
Hope this helps!
Answer:
YES
Step-by-step explanation:
57+45=102.
The triangle needs to have angles that add up to 180 so..
180-102=78
and that is the other degree instead of 45 on the other triangle
