Help! What is the area of each shape?
choli [55]

Answer:

27.84 m² , 42.48 m²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = \frac{1}{2} bh ( b is the base and h the perpendicular height )

Shape A

has b = 9.6 and h = 5.8, then

A = 0.5 × 9.6 × 5.8 = 27.84 m²

Shape B

has b = 11.8 and h = 7.2 , then

A = 0.5 × 11.8 × 7.2 = 42.48 m²

In ΔABC, the lengths of a, b, and c are 22.5 centimeters, 18 centimeters, and 13.6 centimeters, respectively.
Irina-Kira [14]
Given the values of the three sides of the triangle, we can apply the Cosine Law to find the angles of the triangle. Recall that for we can express the value of c through the equation below.

c^{2} = a^{2} + b^{2} - 2abcosC

Rearranging this equation, we can find the value ∠C as shown below.

\cos C = \frac{a^{2}+b^{2}-c^{2}}{2ab}
C = cos^{-1} (\frac{a^{2}+b^{2}-c^{2}}{2ab})

We can apply the same reasoning for finding the value of ∠B as shown.

B = cos^{-1} (\frac{a^{2}+c^{2}-b^{2}}{2ac})

Plugging in the values of the sides (see image attached) from the given. It will now be straightforward to compute for ∠B and ∠C.

C = cos^{-1} (\frac{22.5^{2}+18^{2}-13.6^{2}}{2(22.5)(18)})
C \approx 37.19

B = cos^{-1} (\frac{22.5^{2}+13.6^{2}-18^{2}}{2(22.5)(13.6)})
B \approx 53.13

Answer: ∠C = 37.19° and ∠B = 53.13°

Can someone help me with this? ( solving angle measures)
raketka [301]

Answer:

38°

Step-by-step explanation:

Complementary means that they add up to 90
So then to find the measure of angle 2, subtract the measure of angle 1 from 90.

90-52=<u>38</u>
