Answer:
Step-by-step explanation:
<u>Use the formula:</u>
- A = 1/2Pa, where P- perimeter, a - apothem
<u>Find the area:</u>
- A = 1/2(5*17.6)*12.1 = 532.4 in²
Correct choice is d
Sin x cos x ( tan x - 1) = 0
so one solution is tan x = 1 giving x = 45, 225 degrees ( for x 0 to 360)
sin x cos x = 0 so either sinx = 0 giving x = 0, 180, 360 degrees
or cos x = 0 giving x = 90, 270
answer is 0, 45, 90, 180, 225, 270, 360 degrees ( for 0 =< x >= 360)
Answer:
31.5
Step-by-step explanation:
Area of a rectangle = lw
Substitute: 7*3 = 21
Area of a Triangle = 1/2*bh
Substitute: 1/2*(3)(7) = 10.5
Area = 21 + 10.5 = 31.5
The Hypotenuse Angle Theorem states that if one acute angle and the hypotenuse of the two right angled triangles are congruent then the triangles are congruent.
ADC is congruent to triangle CBA given that ∠D and ∠B are right angles and DC is parallel to AB.
Given: ∠D and ∠B are right angles
DC || AB
Prove: △ADC ≅ △CBA
STATEMENT REASON
1.∠D and ∠B are right angles 1. Given
2. ∠1=∠ 2 2. If lines are parallel, then alternate
Interior angles are equal
3. AC ≅ AC 3. Common to both △s
4. △ADC ≅ △CBA 4. Hypotenuse Angle Theorem
