Answer:

In the given figure , line RP || line MS and line DK is their transversal. ∠DHP = 85°

Find the measures of following angles.

(i) ∠RHD (ii) ∠PHG

(iii) ∠HGS (iv) ∠MGK

ANSWER:

(i) Since, RP is a straight line and ray HD stands on it, then

∠RHD + ∠DHP = 180∘ (angles in a linear pair)

⇒∠RHD + 85∘ = 180∘

⇒∠RHD = 180∘ − 85∘ = 95∘

(ii) Since the straight lines RP and DK intersect at H, then

∠PHG = ∠RHD (Vertically opposite angles)

⇒∠PHG = 95∘

(iii) Since, the line RP || line MS and line DK is their transversal intersecting them at H and G, then

∠HGS = ∠DHP (Corresponding angles)

⇒∠HGS = 85∘

(iv) Since, the straight lines MS and DK intersect at G, then

∠MGK = ∠HGS (Vertically opposite angles)

⇒∠MGK = 85∘

Answer:

Q1 sum of all the angle of a triangle is 180°

so,angle A + angle C+ angle B = 180°

putting the value

53°+ 44°+angle B = 180°

97°+angle B = 180°

angle B = 180°- 97°

angle B = 83°

ii) 83°

Q4 ii) Less than 90 degrees

Q5 iv) non of these
