WILL ANSWER FIRST RIGHT ANSWER AS BRAINIEST
Ket [755]

Answer:

8

Step-by-step explanation:

Considering the given value of sum of interior angles with exclusion of one to be 1070 then we can write it as

1070=180(n-2) where n is the number of sides required here.

Making n the subject of the formula then following step by step

n-2=\frac {1070}{180}

n=\frac {1070}{180}+2\\n=7.9444444444444\approx 8

Therefore, the shape is octagon and it has 8 sides.

Please help me with this question with full solutions!!!
Novay_Z [31]

Answer: Choice C

x/w and z/(y+v)

======================================================

Explanation:

All answer choices have that first fraction with a denominator of w. This implies that AB = w is the hypotenuse. This only applies to triangle ABD.

Focus on triangle ABD. It has an opposite leg of AD = x, when the reference angle is ABD (or angle B for short).

So we can say sin(ABD) = opposite/hypotenuse = AD/AB = x/w

x/w is one of the answers

-----------

Also note how y+v is the same for each denominator in the second fraction. y+v is the hypotenuse of triangle ABC. When the reference angle is ABD (aka angle ABC), the opposite side of this same triangle is AX = z

Therefore,

sin(ABD) = sin(ABC) = opp/hyp = AC/BC = z/(y+v)

z/(y+v) is the other answer

Side note: triangle ACD is not used at all.

Mrs. Hinojosa head 75 ft of ribbon if each of the 18 students in her class gets an equal length of ribbon how long would each pi
Helen [10]

Answer:

4 1/6 ft

Step-by-step explanation:

Since each of the 18 students gets an equal length of ribbon, we need to divide the 75 ft of ribbon into 18 equal parts.

75/18= 4 1/6

Each student gets 4 1/6 ft of ribbon
