Answer:
Step-by-step explanation:
-7x + 12 + (-8x + 48) = 180
-15x + 60 = 180
-15x = 120
x = -8
m<BDC= -7(-8)+ 12 = 56 + 12 = 68
m<CBA = -8(-8)+48 = 64+48 = 112
If a polynomial has more than one variable, then thedegree<span> of that </span>monomial<span> is the sum of the exponents of those variables. In this polynomial, 24xyz, the</span>degree<span> is 3 because the sum of </span>degrees<span> of x, y and z is 1 + 1 + 1 = 3. hope this helps :)</span>
Step-by-step explanation:
in isoscles triangles two angles and lengths are equal .
two sides equal 3.5
so both of the angles are 55°
the sum of the angles in a triangle is 180°, so
x = 180° - 55° - 55°
x = 70° (Ans)
