Answer:

x = 20 (degrees)

y = 70 (degrees)

Step-by-step explanation:

The angle adjacent to the one labeled 40° is supplementary, so it would measure 140°. And the obtuse triangle is an isosceles, which means that x is half of 180° - 140°, so x = 1/2(40°) = 20°

To find y, subtract 90° and x from 180°

y = 180° - 90° - 20°

y = 70°

meriva
Hi there! So, the price is up by 110%. That would mean doubling the price, but that’s not an option. Instead, we can multiply by 110% (1.1) to find the new price of the juice. 2.85 * 1.1 is 3.135 or 3.14 when rounded to the nearest hundredth. The new price of the juice is $3.14. The answer is D.

Leviafan [203]

Answer: 13

Step-by-step explanation:

since the scale is 1cm:5cm and the real distance is 65 it means that you have to use direct variation when the ratio stays the same so the answer would be 65/5 which is 13
