Answer:
135°
Step-by-step explanation:
Since it's a right triangle, one angle will be 90° and the other given one is 45°. The total degrees in a triangle is 180 therefore ∠CAB is 45°.
Because ∠CAB is supplementary to ∠CAD, you have to subtract 180° -- since it's a straight line -- with 45°.
This gives you 135°

B. two
Step-by-step explanation:
Step 1 he had to multiply the $22.75 times 3 weeks it should have been
($22.75 x 3) + $32.75 - $14.25
$68.25 + 32.75 - $14.25
$86.75
Given:
The figure of a triangle DEF.
To find:
The coordinate of image of given triangle after reflection over y-axis.
Solution:
The vertices of given triangle are D(1,4), E(4,3), F(2,0).
If a figure is reflected over the y-axis, then the rule of reflection is

Using this rule, we get



Therefore, the coordinates of image are D'(-1,4), E'(-4,3) and F'(-2,0).
