Answer:
Step-by-step explanation:
90 = (90-x)-x + 74
16 = 90-2x
2x = 74
x = 37 (angle)
90-x = 53 (complement)
Answer: 195
Step-by-step explanation:
Multiply 150 by .3 to get 45
Add 150 to 45 to get 195
Answer:
ST = 7.1 in
Step-by-step explanation:
we can use SOH-CAH-TOA because we've got a right triangle
side ST would be 'adjacent'
side TU would be the 'hypotenuse'
so we use Cosine because that's used when you're dealing with adjacent and hypotenuse:
cos 42° = ST/9.5
ST = cos 42° × 9.5
ST = 7.1
Answer:
a = -2
Step-by-step explanation:
The first equation can be rewritten in slope-intercept form:
5y = -10x +90
y = -2x +18
The value a=-2 will make the second line identical to the first.
