Answer:
(a) 180°
(b) 180°
(c) substitution property
(d) m∠3
(e) ∠3
Step-by-step explanation:
Definition: Two angles are supplementary if they add up to 180°
Proof:
By definition of supplementary angles, m∠1 + m∠2 = 180° (a) {∠1 and ∠2 are supplementary - given}
and m∠2 + m∠3 = 180° (b) {∠2 and ∠3 are supplementary - given}
Then, m∠1 + m∠2 = m∠2 + m∠3 by the substitution property (c)
Subtract m∠2 from each side. You get m∠1 = m∠3 (d)
or ∠1 ≅ ∠3 (e)
Answer:
<h2>A</h2>
Step-by-step explanation:
Look at the picture.
Only from point A do the lines pass through the corresponding vertices of both triangles.
Answer:
33 Km
Step-by-step explanation:
The length of the arc is calculated as
arc = circumference of circle × fraction of circle
= 2πr × 
= 2π × 14 × 
= 28π × ≈ 33 Km ( to nearest Km )
Step 1: Break off 1 from 9
8 3/3 - 2 1/3
Step 2: Subtract the whole numbers
8 - 2 = 6
Step 3: Combine fractions
3/3 - 1/3 = 2/3
6 + 2/3 = 6 2/3
Answer: 6 2/3 yd (D)
Answer:
Step one identify the two points on the line in the graph
Example: (0,2) ( 2,1)
Step two calculate the vertical change from one point to the next
Step three write the ratio vertical change over horizontal change
Example (-1/2 )
