Answer:

1) 29.16

2) 7/2

3) a = 8/25  

4) x = 4/15  

5) d = 23 1/3

Step-by-step explanation:

1) (45+3 3/5 )·0.6 = 48 3/5·0.6  = 29.16

2) (4÷ 4/7) ∙0.3 / (2.88÷4.8)   = (4 ∙7/4)∙0.3 / 0.6  = 7/2

3) 2 1/7 :(15a)= 5/14 :(0.8)

2 1/7 ∙0.8 = 5/14 ∙15a

1 5/7 = 5 5/14 a

1 5/7 : 5 5/14 = a

8/25 = a

4) 3x−1/5 = x+1/3

-1/5 - 1/3 = x - 3x

-8/15 = -2x

-8/15 : -2 = x

4/15 = x

5)(0.3d−1) / (3 1/3)=0.84: 7/15

(0.3d−1) =0.84: 7/15  ∙ 3 1/3

0.3d = 6 + 1

d = 7 :  0.3

d = 23 1/3

In Δ,∠=70°,∠=50° ∠ . <br> ℎ ∠.
AveGali [126]

Answer:

100°

Step-by-step explanation:

A triangle is a polygon shape with three sides. Triangles are of different types such as obtuse, scalene, equilateral, isosceles etc.

In triangle ABC:

70° + 50° + ∠C = 180° (sum of angles in a triangle)

120 + ∠C = 180

∠C = 180 - 120

∠C = 60°

Since ∠C is bisected into ∠ACD and ∠BCD, hence:

∠ACD = ∠BCD = ∠C / 2

∠ACD = ∠BCD = 60 / 2

∠ACD = ∠BCD = 30°

In triangle ACD:

∠A + ∠ACD + ∠ADC = 180° (sum of angles in a triangle)

50 + 30 + ∠ADC = 180

∠ADC + 80 = 180

∠ADC = 100°
