Answer:
60
Step-by-step explanation:
We are given the triangles are congruent, that means the angles are the same measurement
<A = <X
<B = <Y
<C = <Z
We know A = 50 so X = 50
We know <Y = 70 so < B = 70
The three angles of a triangle add to 180
<A + <B + <C = 180
Substituting into the equation
50 + 70 + <C = 180
Combining like terms
120 + <C =180
Subtracting 120 from each side
120-120 +<C =180-120
<C = 60
Answer: 6
Explanation:
Order of Operations means multiplication comes before subtraction so 3x3 = 9
And 15-9 is 6.
You would have to use this equation : y2-y1/x2-x1 = slope
So it would be -13 +3/6-2= -10/4
Simplify it and you get : -5/2
Slope is -5/2
Abc=de
Divide by ab on both sides to get c by itself and find the answer.
c = (de)/(ab)
The compass was kept at the same width to create the acrs for points C and D. - Credit to XCUTE40
