Answer:

x = 45° , y = 72°

Step-by-step explanation:

A straight, horizontal line is equal to 180°

x = 180° - 135°

x = 45°

We can find y because we know that all three angles of a triangle equal 180°

So what do we have?

63°, 45°, y

We can make an equation:

180° - (63°+45°) = y

180°- 108° = 72°

y = 72°

Hope this helped. I will revise any mistakes if needed. Please consider marking brainliest :)

Answer:

X = 45°

Y = 72°

Step-by-step explanation:

There is a supplementary angle (an pair of angles that create a straight line is equal to 180°) and there is the rule that all three angles in a triangle equal 180° as well.

Answer:

B: 5x+5.75

Step-by-step explanation:

2 cones with fruit:

cones= x+x=2x

fruit= $1 x 2=$2

=2x+ 2

3 cones with candy and syrup:

cones= x+x+x=3x

candy= $0.75x3=$2.25

syrup= $0.50x3=$1.50

3x+ (2.25+1.50)

=3x+3.75

both of them together=

(3x+3.75)+(2x+2)= 5x+5.75
