Answer:
Step-by-step explanation:
apply sine rule 2 the triangle on left:
sinB'/10=sin45deg/8.2
sinB'=10*sin45deg/8.2=0.8623
B'=59.58deg or 120.42deg
as shown in the pic, B' > 90deg.
so B'=120.42deg.
the triangle on right has 2 sides at 8.2 so it is isosceles
B=adjacent < of B'
=180-120.42
=59.58deg
Answer:
=3x^7
Step-by-step explanation:
Simplify, 12x^4 ÷ 4 x^3

Answer:
27/35 is the exact answer
7/10 is an estimate
Step-by-step explanation:
4/7+2/10
Simplify the fraction
4/7+1/5
The common denominator is 35
4/7*5/5 + 1/5 *7/7
20/35 + 7/35
27/35
To estimate
4/7 is close to 1/2
2/10 is close is 1/5
1/2 + 1/5 =
5/10 + 2/10 = 7/10
The answer is A. y = [x] -2
