Answer:
The unknown angle is 80
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
Let the unknown angle be x
20+80+x = 180
Add like terms
100+x = 180
Subtract 100 from each side
100-100+x=180-100
x = 80
The value of the modulus function |-3| is 3.
<h3>What is the value of modulus?</h3>
'Modulus' exists a Latin word, which signifies 'measure'. Absolute value is commonly referred to as numeric value or magnitude. The absolute value designates only the numeric value and does not contain the sign of the numeric value. The modulus of any vector quantity exists ever taken as positive and exists in its absolute value.
The absolute value (or modulus) | x | of a real number x stands as the non-negative value of x without regard to its sign.
For example, the absolute value of 5 stands at 5, and the absolute value of −5 exists also at 5. The absolute value of a number may be considered as its distance from zero along a real number line.
Therefore, the value of the modulus function |-3| is 3.

Since 
, the identity is proven.
350-60=290, so Leo needs $290.00 more to buy the phone. 290/20=14.5. Leo needs to cut 15 more yards to have enough money to buy the phone.
Answer:
Step-by-step explanation:
1. 90/360 degrees is 1/4, so quarter turn around point A; this should look like B and C on the top side and then A just stays where it is
2. 180/360 degrees is 1/2, so half turn around point A; A and B are in a horizontal line and C is under point A
3. 270/360 degrees is 3/4, so three-quarters turn around point A; this should look kind of like a slope going uphill where C is the bottom of the slope, A is at the top of the slope, and B is the corner under point A
