Answer:
If the gift card is $30 the remaining change is 3 dollars
Pi/3 is in the first quadrant, and all trigonometric functions are positive in the first quadrant,
Therefore, cos pi/3 is positive.
Answer:
<h3>Q1</h3>
<u>Use slope formula</u>
- m = (y2 - y1)/(x2 - x1)
- m = (-2 - 6)/(3 - 7) = -8 / -4 = 2
- m = 2
<h3>Q2</h3>
Angles 2 and 6 are on the corresponding sides of the parallel lines, hence are corresponding angle
<u>Correct option is </u>
<h3>Q3</h3>
Congruent triangles have congruent corresponding parts
- ΔABC ≅ Δ GHI
- AB≅GH
- AB = GH = 13
<u>Correct choice is</u>
<h3>Q4</h3>
Option b is correct for any line and doesn't make the lines parallel. The rest of the options are correct for parallel lines.
<u>Correct option is the last one:</u>
Angles are the space between intersecting lines, and they are measured in degrees or radians
The measure of angle ABC is y + x
<h3>How to determine angle ABC</h3>
The given parameters are:
ABD=y,
DBC=x,
EFH=y,
EFG=x
PQS = SQR = x
To determine the measure of angle ABC, we make use of angle ABD and angle DBC
Note that angle ABD and angle DBC have common vertices at points B and D
So, we have:
ABC = ABD + DBC
Substitute known values
ABC = y + x
Hence, the measure of angle ABC is y + x
