Answer:

(D) 7

Step-by-step explanation:

It is given that NELR is a parallelogram, then using the property of parallelogram, we have

{\angle}N+{\angle}E=180{\circ} (Sum of Corresponding angles of parallelogram is 180°)

7x+33+11x+21=180^{\circ}

⇒18x+54=180

⇒18x=126

⇒x=7

Therefore, the value of x will be 7.

Hence, option (D) is correct.

Alenkinab [10]

Answer:

The triangle's perimeter is 61.77 inches.

Step-by-step explanation:

Since an altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles, and as a result, the altitude cuts the base into two equal segments, and the length of the altitude is 26 inches, and the length of the base is 9 inches, to find the triangle's perimeter the following calculation must be performed:

Isosceles triangle = 2 equal sides

To obtain the value of the sides, the Pythagorean theorem must be applied on the right triangle formed with the altitude.

(9/2) ^ 2 + 26 ^ 2 = X ^ 2

4.5 ^ 2 + 26 ^ 2 = X ^ 2

20.25 + 676 = X ^ 2

√ (20.25 + 676) = X

√696.25 = X

26.38 = X

26.3865 x 2 + 9 = X

52.77 + 9 = X

61.77 = X

Therefore, the triangle's perimeter is 61.77 inches.
