Answer:

102°

Step-by-step explanation:

Since the triangle is an isosceles triangle, two sides are equal and angle opposite to them are also equal.

Therefore, x°+39°+39°=180°

=> x°+78° = 180°

=> x° = 180-78° = 102°

Simplify (4^7/5^2)^3

Nuetrik [128]

Answer:

4²¹/5⁶ or 4398046511104/15625

Step-by-step explanation:

Remember, when raising a term with an exponent to some power, you must multiply the powers.

$(\frac{4^{7} }{5^{2} })^{3} \\\\ = (\frac{(4^{7})^{3} }{(5^{2})^{3} }) \\\\= \frac{4^{7 * 3} }{5^{2* 3} } \\\\= \frac{4^{21} }{5^{6} } \\\\=\frac{4398046511104}{15625}$

What is the area of the figure?

RUDIKE [14]

The area formula for rectangles is lxw. To solve, I would divide the figure up into 3 rectangles- top,middle and bottom, then find the areas and add them together.

Top: 4x13=52 cm^2
Middle: 5x8=40 cm^2
Bottom: 21x10=210 cm^2

(5 is the width of the middle piece. You get it from subtracting. 21-8-8=5. 13 is the width of the top piece. 5+8=13)

52+40+210
=302 cm^2
So your answer is 302 square centimetres.

Answer: No

Step-by-step explanation: No, because a proportional relationship is a line that goes up at a constant rate, and goes through the origin, an example of a proportional relationship is a straight line starting from the origin ( or what we call the starting point)
