Answer:
The measurement of EF is 1.98 units
Step-by-step explanation:
In Δ DEF
∵ m∠E = 90°
∴ FD is the hypotenuse of the triangle
∵ m∠D = 26°
∵ EF is opposite to angle D
- We can use the sine ratio to find it
∵ sin D = 
⇒ (opposite side / hypotenuse)
∵ FD = 4.5 units
∴ sin(26) = 
- Multiply both sides by 4.5
∴ 4.5 sin(26) = EF
∵ sin 26° ≈ 0.44
∴ 4.5(0.44) = EF
∴ 1.98 = EF
The measurement of EF is 1.98 units
We want the ratio of calories of an orange to a cookie and are told that an orange has 35 calories and a cookie has 130 so:
O:C=35:130
The greatest common factor of 35 and 130 is the product of the shared primes of the numbers prime factorization.
35=5*7 and 130=2*5*13, so the GCF is just 5, so divide each term by 5
O:C=7:26
I’m pretty sure the answer is 12
