Answer:
the answer is 12
Step-by-step explanation:
12÷4 =3-3=0
Answer:
angle BAC = 116
Step-by-step explanation:
since the triangle is isosceles and AB and AC are congruent, that means angle ABC and angle ACB are the same by the isosceles triangle theorem. so you know angle ABC and angle ACB are 32 and all angles in a triangle equal to 180. so you find angle BAC subtracting both of the 32 angles from 180 and you should get 116
I THINK
A. 6 ft²
B. draw a diagonal; each triangle would be half the area: 3 ft²
Step-by-step explanation:
Part A:
The area is the product of the length of one of the parallel sides and its distance from the other:
A = bh = (8 ft)(3/4 ft) = 6 ft²
__
Part B:
A parallelogram can be divided into two congruent triangles by either of its diagonals. Since the triangles are congruent, each will have 1/2 the area of the parallelogram. In this case, each triangle's area would be ...
(1/2)6 ft² = 3 ft²
Answer: 7 11/19 (fraction)
Step-by-step explanation:
Answer:
slope = -
Step-by-step explanation:
Differentiating implicitly with respect to x
2x + 2y = 0
2y = - 2x
= - = -
is the measure of the slope of the tangent
rearrange equation to find corresponding y-coordinate of x = - 2
y² = 16 - 4 = 12 = 2 ⇒ y = ± 2
using x = - 2, y = - 2, then
= - = -
