In the given figure, AB||CD. Find the value of x.

Asked by Santosh.kumar0317 | 19th Aug, 2019, 05:12: PM
Expert Answer:
AB || DC and AC is a transversal.
m
BAC + m
ACD = 1800 (Sum of Co - interior angle is 1800 )
→m
ACD = 1800 - 750 = 1050
m
ECF =m
ACD = 1050 ...(vertically opposite angles)
In ΔCEF,
ECF +
E +
F = 1800 (Sum of all the three angles of a triangle is 1800)
→ 1050 + x + 300 =1800
→ x = 450

- In a triangle ABC, if angle A + angle B = 65 and angle B + angle C = 140 , then the measure of angle B is (a) 40 (b) 25 c) 115 (d) 60
- one exterior angle of a triangle is 110 degree and one ko interior opposite angle is 30 degree find the remaining angles of the triangle
- What is angle sum property
- answer to all question
- Please answer this question
- Can a triangle have (i) Two right angles? (ii) All angles less than 60o? (iii) All angles equal to 60o? (iv)Two acute angles? Justify your statement in each case.
- If the bisectors of
B and
C of triangle of a
ABC intersect at O, then prove that
BOC = 90o +
.
- The sides AB and AC of a triangle are produced to D and E respectively. The bisectors of
CBD and
BCE meet at O. If
A = 40o, find
BOC.
- In triangle ABC, if
A +
B = 108o and
B +
C = 130o, find
A,
B and.
C
