basically write the triangle in degree language like this is a acute angle because this is a 70* degree angle and talk more
Answer:
Sydney is 44 years old
Step-by-step explanation:
<u>Step 1: Make a system of equations
</u>
d = s - 15
<em>d + s = 73
</em>
<u>Step 2: Plug in s - 15 for d in the second equation and solve
</u>
s - 15 + s = 73
2s - 15 = 73 + 15
2s / 2= 88 / 2
<em>s = 44
</em>
Answer: Sydney is 44 years old
Answer: d) 14
Step-by-step explanation:
Equation of a line passing through (a,b) and (c,d):
Equation of a line passing through (2, 18) and (–3, 8):
Comparing resulting equation to , we get value of b= 14.
Hence, correct option is d) 14
Answer:
Set it up using the slope from the two points. (c - (-5))/3 - 1 = slope = (c + 5)/2. Now put this into slope intercept since they give you the y intercept of 7. y = x*(c + 5)/2 + 7. Now put in the point, (1,-5). -5 = 1*(c+5)/2 + 7. Subtract 7 from both sides. Now multiply through and you can solve for c.
