Answer:
sin(x) and cos(y) are equal and have ratio of 1 : 1
First find the missing hypotenuse using Pythagoras theorem:
a² + b² = c²
12² + 5² = c²
c = √144+25
c = 13
using sine rule:
using cosine rule:
Answer:
Step-by-step explanation:
A+N+J=310
A=N*2 =>N=A/2
N=J*3 =>J=N/3
N=?
N*2+N+N/3=310
3N+N/3=310
(9N+N)/3=930/3
10N=930
N=930/10
N=93

Answer:
The subtraction property of equality
Option A is correct
Explanation:
The given equation is:
12 - x = 7x + 32
Subtract 12 from both sides
12 - 12 - x = 7x + 32 - 12
-x = 7x + 20 (Step 1)
From step 1 above, subtract 7x from both sides
-x - 7x = 7x - 7x + 20
-8x = 20 (Step 2)
Since we subtracted 7x from both sides to get step 2, the justification for step 2 is the subtraction property of equality
Since a yard equals 3 feet, it would take him 73.1 seconds to finish the dash.
