Answer:
Hence x = y = 2
Step-by-step explanation:
Using the SOH CAH TOA identity
Hypotenuse = 2√2
Opposite = x
theta = 45
Sin theta = opp/hyp
Sin 45 =x/2√2
1/√2 = x/2√2
x = 2√2 * 1/√2
x = 2
To get y we will use the pythagoras theorem;
(2√2)² = x² +y²
(2√2)² = 2²+y²
8 = 4 + y²
y² = 8-4
y² = 4
y = √4
y = 2
Hence x = y = 2
Answer:
-0.4
Step-by-step explanation:
If using a number line, start at 0.2 and go backwards 0.6 to get to -0.4
Hi there,
4x - 5y = 39
y = 6x - 13
4x - 5(6x - 13) = 39
4x - 30x + 65 = 39
-26x = 39-65
-26x = -26
x= -26/-26
x= 1
So we deduce y now :
y = 6 *1 - 13
y= 6 - 13 = -7
Hope this helps !
