Answer:
40,000 ml
Step-by-step explanation:
1 liter = 1000 ml
so 40 x 1000 = 40000
Answer:
35.18
Step-by-step explanation:
Answer:
Step-by-step explanation:
we know that
The inscribed angle is half that of the arc it comprises.
step 1
Find the measure of the arc PQR
![109^o=\frac{1}{2}[arc\ PQR]](https://tex.z-dn.net/?f=109%5Eo%3D%5Cfrac%7B1%7D%7B2%7D%5Barc%5C%20PQR%5D)
step 2
Find the measure of arc QR
we have
substitute
step 3
Find the measure of the arc QRF
![112^o=\frac{1}{2}[arc\ QRF]](https://tex.z-dn.net/?f=112%5Eo%3D%5Cfrac%7B1%7D%7B2%7D%5Barc%5C%20QRF%5D)
step 4
Find the measure of arc RF
we have
substitute
Answer:
3. 37
4. 59
5. 79
Step-by-step explanation:
All the angles of the triangle add up to 180°
3. 180-(31+112) = 37°
4. (4x-18)+(8x+7)+(5x+4) = 180
17x-7 = 180
17x = 187
x =11
we have found the x now we need to input it to find m∠z
5x+4
=5×11+4
=59°
5. A straight angle is 180° so if the outside angle is 129 the inside one will be 51°
(2x-3)+(x+9)+51 = 180
3x+57 = 180
3x = 123
x = 41
Now we need to find m∠L
2x-3
= 2×41-3
= 79°
Because the 18-gon is symmetrical, you can rotate it by 360/18 or 20 degrees. This is because when you rotate it by 20 degrees(to the left for explanation matters), any angle will now be in the position of its angle to its left.
