Answer:
Easy -2x
Step-by-step explanation:Because both a positive y and a negative y cancle out eachother so all thats left is both of the negative x's
The correct answer is option B which is we need ∠L ≅ ∠R to prove congruency.
<h3>What is congruency?</h3>
The Side-Angle-Side Congruence Theorem (SAS) defines two triangles to be congruent to each other if the included angle and two sides of one is congruent to the included angle and corresponding two sides of the other triangle.
According to the SAS theorem which means Side Angle Side, The angle which is included between the two sides must be congruent.
Here we are given that
KL = NR
JL = MR
Now in the figure, we can clearly see that the angle included between JL & KL is L & the angle included between NR & MR is R.
So for the triangles to be congruent by SAS, angle L must be congruent to angle R.
∠L=∠R
Therefore the correct answer is option B which is we need ∠L ≅ ∠R to prove congruency.

Answer:
The measure of angle YUV is equal to 
Step-by-step explanation:
see the attached figure to better understand the problem
we have that
-----> given problem
so
------> by central angle
we know that
The triangle UZV is an isosceles triangle
because

so
-----> bases angle of the isosceles triangle
Remember that
The sum of the internal angles of a triangle is equal to 
so


substitute and solve for m<ZUV


------> by complementary angles
solve for m<YUZ


Answer:
Option (3)
Step-by-step explanation:
To prove ΔULV ≅ ΔKLY,
Statements Reasons
1). VL ≅ LY 1). Radii of a circle are equal
2). UL ≅ KL 2). Radii of a circle are equal
3). ∠ULV ≅ ∠KLY 3). Vertical angles are equal
4). ΔULV ≅ ΔKLY 4). SAS property of congruence
Therefore, property (3) given in the options will be used to prove the triangles congruent.
Answer:
1200
Step-by-step explanation:
Find the width and the height show in the picture then use the formula Area = length X height
The width is 40 and the height is 30. Therefore Multiply it together and get 1200
