(4x+28)+(x+19)+(3x+13)=180
8x+60=180( combine like terms)
8x+60-60= 180-60
8x=120
8/8x=120/8
x=15
The missing angles are 88°, 34° and 58°

HELP ASAP PLEASE

Solution (1) using angles of sectors:

Area of A = pi r^2  x 90/360 = 4.9

Area of B = pi r^2 x 270/360 = 14.2 


Check:  Area of A/B = 4.9/14.72 = 1/3 (as given)

Solution (2) using given info:

Area of B + Area of A = area of circle

Area of B + 1/3 Area of B =  3.14 * (2.5)^2 = 19.625

4/3 Area of B = 19.625

Area of B = 3/4 * 19.625

Area of B = 14.72

Area of A = 1/3 * 14.72 = 4.9

There is more solutions to this problem , like polar coordinate integration , and so on. for more just request.

The quadratic equation -6=x^2+4x-1 in Standard form . What is the value of c in his new equation
Vitek1552 [10]

Answer:

c = 5

Step-by-step explanation:

A quadratic equation in standard form is

ax² + bx + c = 0 : a ≠ 0

Given

- 6 = x² + 4x - 1 ( add 6 to both sides )

0 = x² + 4x + 5 ← in standard form

with c = 5
