(2x - 6) + (x+ 10) + (2x + 1) = 180
2x - 6 + x + 10 + 2x + 1 = 180
2x + x + 2x = 180 + 6 - 10 - 1
5x = 175
x = 35
Answer:
4. 480.38m² 6. 3.35
Step-by-step explanation:
Assuming you're looking for the area of the shaded region, you must first be aware that the entire circle has a 360 angle.
From there. for no. 4:
You subtract 87 from 360 to find the angle of the major arc.
360-87=273
From there you must also know the formula to find the area of a sector which is:
(x/360)×pi×r²
In our case 273 is x and 14.2 is r so
(273/360)×pi×14.2²= 480.38
Do the same steps to find 6
