Answer:

(d) A = 18 units²

Step-by-step explanation:

Line CE can be considered to be the base of two triangles. It is 6 units long. The upper triangle is 4 units high, and the lower triangle is 2 units high. The formula for the area of a triangle is ...

A = 1/2bh

Then the sum of the areas of the two triangles is ...

A = 1/2(6)(4) +1/2(6)(2) = 12 +6 = 18

The area of the polygon is 18 square units.

calculate the side lengths a and b to two decimal places angle a is 64 angle b is 85 and line ab is 9.3? PLEASE HELP ASAP

qaws [65]

∠C = 180° - (∠A + ∠B) = 180° - (64° + 85°) = 180° - 149° = 31°
$AC= \frac{9.3*sin(85)}{sin(31)} = \frac{9.3*0.9962}{0.515} =17,99 \\ \\ BC=\frac{9.3*sin(64)}{sin(31)} = \frac{9.3*0.8988}{0.515} =16,2$

Answer:

C. 3.0

Step-by-step explanation:

Lets calculate the points:

Art - 2 hrs - B (3) ⇒ 2*3 = 6 points
History - 3 hrs - A (4) ⇒ 3*4 = 12 points
Science - 4 hrs - C (2) ⇒ 4*2 = 8 points
Math - 3 hrs - B (3) ⇒ 3*3 = 9 points
Lab - 1 hr - A (4) ⇒ 1*4 = 4 points

Totals

Total hours = 13
Total points = 39

GPA = total points/ total hours

GPA = 39/13 = 3.0

Correct option is C
