Answer:
Part a) <1=72°
Part b) <2=108°
Part c) <3=72°
Part d) <4=108°
Step-by-step explanation:
step 1
Find the measure of angle 1
we know that
<1+108°=180° -----> by supplementary angles
so
<1=180°-108°=72°
step 2
Find the measure angle 2
we know that
<2=108° -----> by corresponding angles
step 3
Find the measure angle 3
we know that
<3=<1-----> by corresponding angles
so
<3=72°
step 4
Find the measure angle 4
we know that
<4=108° -----> by alternate exterior angles
Answer:
x = 30
Step-by-step explanation:
30 + 2x = 90
2x = 60
x = 30
Answer:
The first one is n=4,-1
Second one in exact form
Second one in decimal form
Rigid transformation do not alter the sides and angle measurements of a shape.
The true statements are:
- <em>quadrilateral 1 and quadrilateral 2 - Not congruent
</em>
- <em>quadrilateral 1 and quadrilateral 3 - Not congruent
</em>
- <em>quadrilateral 1 and quadrilateral 4 - Not congruent
</em>
- <em>quadrilateral 2 and quadrilateral 3 - Congruent
</em>
<em />
From the graph, we have the following highlights
- Quadrilaterals 2, 3 and 4 are congruent
- Quadrilateral 1 does not have equal measure with any of the other quadrilaterals.
Hence, the first three statements are not congruent, while the last statement is congruent.

Yes because they both give you an x =2 and a y=-4
