Answer:
x = 5.4
Step-by-step explanation:
The marked sides are the hypotenuse and the side adjacent to the marked angle. That suggests the appropriate trig function is the cosine:
Cos = Adjacent/Hypotenuse
cos(19°) = 5.1/x
x = 5.1/cos(19°) . . . . . multiply by x/cos(19°)
x ≈ 5.4
Answer:
Total lizards in the store are 64.
Step-by-step explanation:
Total food that Sara owns for the pet = 4.25 pounds
One pound of food is needed for the number of lizards = 15
Now we are required to find the number of lizards in the store. To find the number of Lizards we must multiply the total food with the number of lizards for one pound food.
Total lizards = Total food × lizards for one pound food.
Total lizards = 4.25 × 15
Total lizards = 63.75 or 64 lizards.
