  • Measure of angle C = 100°
  • Measure of angle A = 40°
  • We know, sum of all angles of a triangle is 180°.
  • Therefore, the measure of angle B

= [180 - (100 + 40)]° = 40°

  • When two angles of a triangle are equal, then the triangle is isosceles.
  • Here, the measure of angle A and B are equal, i.e., 40°
  • So, ∆ABC is an isosceles triangle.

Here you have a system of 2 equations and 2 unknowns. An easy way to solve this type is to isolate one of the variables.

12a + 2b = 8
2b = 8 - 12a
b =
b =  \frac{8 - 12a  }{2}
b = 4 - 6a

Now plug 4 - 6a into equation 1 to solve for a.

a + 5(4 - 6a) = 19

a + 20 - 30a = 19

-29a = -1

a = 1/29 (answer)

Now plug a into the equation for b

b= 4 - 6(1/29)

b= 110/29 (answer)

Answer:

x= 2.28

or, x= 0.219

Step-by-step explanation:

2x²-5x+1 =0

a= 2, b= -5 and c= 1

x= (-b <u>+</u> √(b²-4ac))/2a

= (5 <u>+</u> √(25-8))/4

= (5 <u>+</u> √17)/4
