Answer: B = 70°, b = 29.2; c = 29.2
Step-by-step explanation:
sum of angles in a triangle is 180
40+70 +X = 180
X is the last angle
110+x=180
x= 180-110 =70
A= 40°
B= 70°
C= 70°
the triangle is Isosceles triangle meaning two sides are equal , angle B = angle C
Step-by-step explanation:
2 and 5 are coefficients
2x+3 is a sum
2x, 4, 3, and 5y are terms
(2x+3) ÷ 5y is a quotient
4(2x+3), 2x and 5y are products
2,4,5,x,y are factors
