Expert Answer:
AB || DC and AC is a transversal.
m
BAC + mACD = 1800 (Sum of Co - interior angle is 1800 )
→mACD = 1800 - 750 = 1050
mECF =mACD = 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
BAC + mACD = 1800 (Sum of Co - interior angle is 1800 )ACD = 1800 - 750 = 1050 ECF =mACD = 1050 ...(vertically opposite angles) ECF + E + F = 1800 (Sum of all the three angles of a triangle is 1800)Answered by Yasmeen Khan | 19th Aug, 2019, 05:46: PM

- 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.
