These 2 angles are supplementary so we have
x+ 88 + x + 108 = 180
2x + 196 = 180
2c = -16
x = -8
the 2 angles are -8+88 and -8+108
that is 80 and 100.
Answer & Step-by-step explanation:
In order to solve this problem, it is important that we know the original form of this equation.
<em>(x - x1)² + (y - y1)² = r²</em>
The equation we are given is: <em>(x - 1)² + (y + 20)² = 196</em>
Now that we know the original equation and the given equation, then we can conclude that the center of the circle is (1, -20). We can find the radius by calculating the square root of 196.
√196 = 14
So, the radius is 14.
Now, based on the given information, we know that the center of the circle is (1, -20) and the radius of the circle is 14.
Considering the values of the digits in the number, we have that digit 2 has a value that is 1/10 the value of the 7 in the ten thousand place.
<h3>What are the values of the digits in the number 1,377,207?</h3>
We start counting the values from the final number, from 1 and multiplying by 10, hence:
- Digit 7 has a value of 1.
- Digit 0 has a value of 10.
- Digit 2 has a value of 100.
- Digit 7 has a value of 1,000.
- Digit 7 has a value of 10,000. -> Ten thousand place.
- Digit 3 has a value of 100,000.
- Digit 2 has a value of 1,000,000.
One tenth of the ten thousand place is a value of 100, hence digit 2 has a value that is 1/10 the value of the 7 in the ten thousand place.

Answer:
5,120 cm³
Step-by-step explanation:
Volume = Base area × height
Base area = 160 cm²
Height = 32 cm
Vol. = 160 × 32
= 5,120 cm³
We are given ratio nickel to zinc to copper = 2:7:9.
From this ratio we can see that <em>ratio of nickel to zinc is 2:7</em>.
Let us assume number of pounds of nickel have to be used to create alloy that contains 4.9 lb of zinc is x pounds.
So, we can setup a proportion as :
x : 4.9 = 2:7
Or
On cross multiplication, we get
7x= 4.9× 2
7x = 9.8
Dividing both sides by 7, we get
x = 1.4.
<h3>Therefore, 1.4 pounds of nickel have to be used to create alloy that contains 4.9 lb of zinc.</h3><h3 />
