The chapter 7 test will have 20-30 questions on it. Novanet!
True! they are corresponding angles.
36/2=18
18 would be your answer the radius is half of the diameter
Answer: -2a + 3b
Solution:
3b - 2a
Simplify
= -2a + 3b
Answer:
To find cosθ, use the formula for the area of a triangle i.e. AREA=1/2 x a x b x sinC.=> For this case: 15= 1/2 x 10 x 5 x sinC to find sinC.=> SinC = 3/5 thus, Arcsin(3/5)=+- 4/5 or +-0.8
To find the exact length of BC, use the cosine rule.=> c(sq)=a(sq)+b(sq)-2abCosC=> c(sq)=10(sq)+5(sq)-2(10)(5)(+-4/5)=> c(sq)= Square root of 205
