-2(3)(5+3-8-3(3))
=-6(5+3-8-9)
=-30-18+48+54
=54
The area of a triangle is base length x height then divide all by 2,
so 12 x 10 /2
=60 ft²
B
Its because when you rearrange using this formula y=mx+c, where m is slope, if m is negative then that line has a negative slope
The answer is B because C and D are not true. Angle-Angle theorem does not prove congruency. Hypotenuse-Leg does because having a hypotenuse means that the triangle is a right angle triangle, which means that 2 sides and an angle are congruent in the triangles. By Side-Side-Angle Theorem, the triangles are congruent.
Answer:
40
Step-by-step explanation:
AFE=120 so arc AE is also 120
those 3 angles add up to 180 and 180-120-20=40
