Answer:
your answer should be 45
Step-by-step explanation:
Answer:
120 degrees.
Step-by-step explanation:
All the angles in a triangle add up to 180. You have two of the angles given:
50 degrees and 70 degrees
To find the third angle of the triangle (BAC), use the expression:
180 - (50 + 70)
180 - 120
60
So, the third angle in the triangle is 60 degrees. Looking at angle DAB, you can see that it forms a straight line with angle BAC. A straight line is 180 degrees. Since we know BAC is 60, and BAC + DAB = 180, by doing 180 - 60, you can see that angle DAB is 120 degrees.
Answer:
1) B) a = 14
2)D) x = -11
3)B) x = 8
4)A) 250 = 3c-20
5)D)8
6)B), C), D)
8)A) 14 months
9)Sarah = 40 years
Sarah = 5/4 x Tanya
40 = 5/4 x Tanya's age
Therefore Tanya's age is 32 years old
Hope this helps you!
