Answer:
The measure of the 2 angles are 90° and 35°.
Step-by-step explanation:
The sum of angles in a triangle is 180°.
2x + x - 10 + 55 = 180
Simplify.
3x + 45 = 180
Find 3x.
3x = 180 - 45
= 135
Find x.
x = 135 ÷ 3
x = 45
2x° = 45° × 2
= 90°
(x-10)° = 45° - 10°
= 35°

Answer: 36 square centimeters
Step-by-step explanation: Hey there! Let's cut the shape in half horizontally. 6 times 4 for the top portion is 24 square centimeters. We subtract 6 cm from the top by 2 cm from the lower part to get the length of the bottom rectangle. We do 4 times 3 for the area of the bottom rectangle which is 12 square centimeters. Finally, we add 24 sq cm and 12 sq cm to get 36 square centimeters. (I tried my best!)
Y=250+2x is the amount she spends
y=12x is the amount she makes
If the amount she spent = the amount she makes then she break even
250+2x=12x
250=12x-2x
250=10x
So x = 250/10=25 necklaces she needs to sell to break even
Answer is 25 necklaces
