Step-by-step explanation:
003:
To solve this, we'll be using the Pythagorean theorem,
004:
For the next couple questions we'll be using a fun rule called SOHCAHTOA, which stands for Sin (Opposite/Hypotenuse) Cos (Adjacent/Hypotenuse) Tan (Opposite/Adjacent). From this we can see that Tan θ is 8/.
005:
From this rule again, we can tell that sin Ф (Opposite/Hypotenuse) is going to be /15.
Answer:
003:
004: 8/
005: /15
Answer:
5(12) + 3.50
Step-by-step explanation:
There are 5 tickets that cost 12 dollars each so you multiply. Then you add 3.50 because of the fee
Answer:
106 cm²
Step-by-step explanation:
the surface area is the sum of the areas of the faces of the prism
area of 2 rectangles (left/ right ) = 2 × 7 × 5 = 70 cm²
area of central rectangle = 3 × 7 = 21 cm²
area of 2 congruent triangles = 2 × × 3 × 5 = 3 × 5 = 15 cm²
surface area = 70 + 21 + 15 = 106 cm²
