X
45
109
64
180
71
Answer:
A
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
x is an exterior angle of the triangle, thus
x = 64° + 45° = 109° → A
Answer:
A
Step-by-step explanation:
64+45=109
180-109=71
180-71=109 *

How to calculate the area of this?
Answer:
1601 m²Step-by-step explanation:
Split the quadrilateral into 2 triangles as pictured
One of them is right triangle with 2 sides known
The third side is the hypotenuse and is:
√(60²+25²) = √4225 = 65 mTotal area is the sum of the areas of the 2 triangles
A= A1 + A2Area 1
A1 = 1/2*15*60 = 750 m²Use Heron's formula for the second triangle:
A2 = 1/4√(65 + 64 + 27)(-65 + 64 + 27)(65 - 64 + 27)(65 + 64 - 27) ≈ 851m²Total area
A = 750 + 851 = 1601 m²Janet bought g number of packs of gum. Each pack of gum costs $0.79. Write an expression that shows how much change she will get back from paying with a $20 bill.

Step-by-step explanation:
the cube of twice a number
Answer:
The cube of twice a number.
Twice a quantity usually indicates to take two of the things in question; usually this indicates to multiply by 2. Thus "twice a number x" can be written symbolically as 2x. If this is part of a problem, say twice a number x is 6, then we can rewrite algebraically as 2x=6; dividing both sides by 2 yields x=3.
