Answer:
1. 60
2. 36
6. 57
Step-by-step explanation: For number 2 and 6 I subtracted the numbers by 90 because one side of the triangle is 90 degrees.

Answer:
B. y = 1.5x +8
Step-by-step explanation:
You can try x=4 in the various equations to see which gives the right value (14).
__
A: y = -8(4) +1.5 = -30.5
B: y = 1.5(4) +8 = 14 . . . . . . . . . this equation works
C: y = 8(4) +1.5 = 33.5
D: y = -1.5(4) +8 = 2
__
Alternatively, you can use the 2-point form of the equation of a line to write the equation:
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (20 -14)/(8 -4)(x -4) +14 . . . . fill in (x1, y1) = (4, 14); (x2, y2) = (8, 20)
y = 1.5(x -4) +14 . . . . . simplify somewhat
y = 1.5x +8 . . . . . . . . write in slope-intercept form
Answer:
18 cm
Step-by-step explanation:
The diameter of M is 76, so that means MK is 76/2 since MK is the radius
MK =38
The diameter of J is 64, so that means JL is 64/2 since JL is the radius
JL =32
JK + KL = JL
Substituting what we know (JK =12 and JL =32)
12+ KL = 32
Subtracting 12 from each side
12-12 + KL =32-12
KL =20
We want to find LM
KL + LM = KM
20 + LM = 38
Subtract 20 from each side
20-20 + LM =38-20
LM = 18
