When I solved it, I got 26 as b. Hope that helped!
Answer:
Option A.
Step-by-step explanation:
step 1
Find the value of x
we know that
If AB is a mid-segment, then AB is parallel to YZ
so
Triangles AXB and YXZ are similar by AA Similarity Theorem
Remember that
If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
In this problem
we have that
----> by Midpoint Theorem
substitute the given values in the expression above
solve for x
Multiply by (2x+2) both sides
Group terms
step 2
Find the length of AB
substitute the value of x
Answer:
'y' would be 24
'x' would be 12
Step-by-step explanation:
the ratio of sides in a 30-60-90 triangle is, respectively, 1 : : 2
so the side across from the 60 degree angle is times the side of the 30°
the side across from the 90 degree angle is double the side of the 30°
so in this problem 'y' would be 24 and 'x' would be 12
1. The interior angles of any triangle add to 180 degrees in measure. So
Then by the law of sines,
2. By the law of sines,
so that
Then
so that
Answer:
the probability that his mother would return on time to catch Gabe stealing is given by:.
Step-by-step explanation:
probability is given by; the required outcome over the number of possible outcome.
Step1; we have to subtract the first initial 30 secs that Gabe spent wondering if he will be caught. i.e 90 sec-30 secs= 60 Sec.
Step2: we divide the number of seconds that he can finish a cookie without being caught over the number of seconds left before his mother returns. that is why we have
