A quadrilateral has angles that measure 60°, 95°, and 150°.
Nikolay [14]
The sum of angles in a quadrilateral = 360 degrees.

Let the fourth angle be x:

Therefore:  60 + 95 + 150 + x = 360

305 + x = 360

x = 360 - 305

x = 55

Option B. I hope this helps.

Mariulka [41]

Answer:

610 feet

Step-by-step explanation:

From the question :

1 scarf = 2.5 yards of yarn

84 scarves = x yards

Cross Multiply

1 scarf × x yards = 84 × 2.5 yards

x yards = 210 yards

Hence, 84 scarves require 210 yards

Converting yards to feet

1 yard = 3 feet

210 yards = x feet

x feet × 1 yard = 210 yards × 3 feet

x feet = 210 yards × 3 feet/1 yards

x feet = 610 feet

Hence, if Janet wants to make 84 scarves, she need to buy 610 feet of yarn
