Answer:
Step-by-step explanation:
Let Kat reads k pages of the book.
Miguel reads 5 times as many pages of the book as Kat. So,
m = 5k ...(1)
Together they read 54 pages. i.e.
m+k = 54 ...(2)
From equation (1),
Hence, the equation that can be used to find how many pages Kat read is equal to 
.
Answer:
2 is the degree
Step-by-step explanation:
The degree of an equation is the highest exponent
Answer:
148 is the surface area
Step-by-step explanation:
12 x 4 = 48
8 x 4 = 32
17 x 4 = 68
48 + 32 + 68 = 148
Not sure if you wanted the exact value or the degrees. Here’s both:
1: sin pi/3 = 60° or sqrt of 3 over 2
2: cos 2pi/3 = 120° or -1/2
3: tan 7pi/4 = 315° or -1
4: tan 5pi/6 = 150° or -sqrt of 3 over 3
5: sin 7pi/6 = 210° or -1/2
6: cos 11pi/6 = 330° or square rt of 3 over 2
Formula I used:
Problem (example: 11pi/6) times 180° over pi.
