Answer: C. 124
Step-by-step explanation:
In parallelograms, any two consecutive interior angles add to 180 degrees. CDA and BCD are consecutive interior angles. Since the measure of angle CDA is 56 and the sum of CDA and BCD equal 180, then to find the value of BCD, evaluate 180-56.
180 - 56 = 124
Answer:
Option B
Step-by-step explanation:
From the picture attached,
In ΔABC,
m∠B = m∠C = 75° [Isosceles triangles]
By applying triangle sum theorem,
m∠A + m∠B + mC = 180°
m∠A + 75° + 75° = 180°
m∠A = 180° - 150°
m∠A = 30°
In triangle PQR,
m∠P = m∠Q [Isosceles triangle]
By applying triangle sum theorem,
m∠P + m∠Q + m∠R = 180°
2(m∠P) + 30° = 180°
m∠P = 75°
m∠P = m∠Q = 75°
In ΔABC and ΔRPQ,
m∠B ≅ m∠Q [Given]
m∠C ≅ m∠R [Given]
Therefore, by AA property of similarity of two triangles, both the triangles will be similar.
ΔABC ~ ΔRPQ
Option B will be the answer.
Answer:
-0.2*-1.5=0.3
Step-by-step explanation:
because it's supposed to be a negative number to bounce back to positive and the 1.5 because it can't be a whole number because it is a three
Answer:
-5/2x+3
Step-by-step explanation:
you reciprocate the slope since you are trying to find a line perpendicular.
From this m=2/5 to -5/2
then use the formula y-y1 =m(x-x1)
then you put in the points
y - - 2= -5/2(x- 2)
y+2= -5/2x +5
-2 -2
y= -5/2+ 3
