Answer:
-11/3
Step-by-step explanation:
Answer:
32units²
Step-by-step explanation:
find the area if the square
2×2 = 4
now find the area of the 3 triangle's
A = 1/2bh
A = 1/2×2×2
A = 2
A = 1/2bh
A = 1/2×6×2
A = 6
A = 1/2bh
A = 1/2×10×4
A = 20
add all the areas up
20 + 6 + 2 +4 = 32
32units²
Answer: 6/13
Step-by-step explanation: a/a+b = 6/6+7 = 6/13
(tanθ + cotθ)² = sec²θ + csc²θ
<u>Expand left side</u>: tan²θ + 2tanθcotθ + cot²θ
<u>Evaluate middle term</u>: 2tanθcotθ =
= 2
⇒ tan²θ + 2+ cot²θ
= tan²θ + 1 + 1 + cot²θ
<u>Apply trig identity:</u> tan²θ + 1 = sec²θ
⇒ sec²θ + 1 + cot²θ
<u>Apply trig identity:</u> 1 + cot²θ = csc²θ
⇒ sec²θ + csc²θ
Left side equals Right side so equation is verified
