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°

My little sister needs help in this and I don't remember. ​
Anna71 [15]
You have to have the same denominator for both fractions, so I would multiply 3/4 by 3 that would give you 9/12 and the other one is 7/12. This means that the final answer would be 9/12>7/12.

Please help :( Calculate each mountain path grade to the nearest percent.
wariber [46]
The grade of the path in the mountain is calculated by determining first the ratio between the rise over the run and multiplying the ratio by 100%. 

For Path A: 

                 grade = (rise / run) x 100%
                 grade = (1414/ 3535) x 100% = 40%

<em>Answer: 40%</em>

For Path B:
              grade = (rise / run) x 100%
              grade = (4.26 m/ 22 m) x 100% = 19.36%

Answer: 19.36%
