Answer:
cosθ = -√(35/36)
tanθ = -1/√35
Step-by-step explanation:
We know that
sin²θ + cos²θ = 1
(1/6)² + cos²θ = 1
1 - (1/6)² = cos²θ
35/36 = cos²θ
sec θ = 1/ cosθ
1/ secθ = cos θ
Because secθ < 0, 1/ secθ would also be < 0, so cos θ < 0
cosθ = -√(35/36)
tanθ = sinθ/cosθ = (1/6)/-√(35/36)
= (1/6) / -(√35/6)
= -1/√35
The answer is 248. Working out is in the picture.
The amounts for each donut are given as follows:
<h3>How to obtain the amounts?</h3>
The amounts for each donut are found applying the proportion, multiplying the decimal equivalent of each percentage by the total number of donuts.
From the problem, the total number of donuts is given as follows:
100 donuts.
The percentages of each type of donuts are given as follows:
The decimal equivalent of each percentage is given as follows:
Hence the amounts are given as follows:
- Strawberry: 15, as 0.15 x 100 = 15.
- Chocolate: 45, as 0.45 x 100 = 45.
- Sprinkle: 40, as 0.4 x 100 = 40.

Answer:
Hello! answer: 39
Step-by-step explanation:
Formula for triangles area: base × height ÷ 2
Formula for squares area: base × height
5 × 3 = 15 15 ÷ 2 = 7.5 since there are 4 triangles that are the exact same I will just multiply by 4 so I have all the triangles so 7.5 × 4 = 30 now the square is just 3 × 3 so... 3× 3 = 9 now we add these up 30 + 9 = 39 therefore the surface area is 39
