Answer:
a=sqrt[50]; ?=50
Step-by-step explanation:
Using the Pytagorean theorem in the right triangle:
A^2+B^2=C^2, with A=a, B=a, and C=10
Replacing in the formula:
a^2+a^2=10^2
Adding like terms:
2a^2=100
Solving for a: Dividing both sides of the equation by 2:
2a^2/2=100/2
a^2=50
Square root both sides of the equation:
sqrt(a^2)=sqrt(50)
a=sqrt(50)
4) S and Q
The scatter plot has a generally negative trend, and most points fall on a line between those points.
Answer:
- arc BF = 76°
- ∠M = 31°
- ∠BGE = 121°
- ∠MFB = 111°
Step-by-step explanation:
(a) ∠FBM is the complement of ∠FBC, so is ...
∠FBM = 90° -52° = 38°
The measure of arc BF is twice this angle, so is ...
arc BF = 2∠FBM = 2(38°)
arc BF = 76°
__
(b) ∠M is half the difference between the measures of arcs BE and BF, so is ...
∠M = (1/2)(138° -76°) = 62°/2
∠M = 31°
__
(c) arc FC is the supplement to arc BF, so has measure ...
arc FC = 180° -arc BF = 180° -76° = 104°
∠BGE is half the sum of arcs BE and FC, so is ...
∠BGE = (1/2)(arc BE +arc FC) = (138° +104°)/2
∠BGE = 121°
__
(d) ∠MFB is the remaining angle in ∆MFB, so has measure ...
∠MFB = 180° -∠M -∠FBM = 180° -31° -38°
∠MFB = 111°
