Answer:
6.4 ft
Step-by-step explanation:
the sine ratios in every triangle are
a/sin(A) = b/sin(B) = c/sin(C)
here now the names are changed.
j = a = 7 ft
m = b
k = c
J = A = 45 degrees
M = B = 40 degrees
K = C
we are trying to find m (= b) based on these numbers.
m/sin(40) = 7/sin(45)
m = 7 × sin(40)/sin(45) = 6.4 ft
Hello! Expanded form is when you write an addition problem by place value in order to get the sum for the answer. For example, expanded form of 123 is 100 + 20 + 3. In this case, 92.3 is out number we are going to expand in addition form. 92.3 in expanded form is 90 + 2 + 0.3. This is because 9 in the tens place has a value of 90, the 2 in the ones place has a value of 2, and the value of 3 in the tenths place has a value of 0.3.
Answer:
A = 40.0 (3 sig. fig)
C = 40
c = 15
Step-by-step explanation:
Using sin law,
sinA/15 = sin100/23
A = 40.0 (3 sig. fig)
Using angle sum of triange,
C = 180 - 40.0 - 100 = 40
Since angleA = angleC, by side equal opp angles, c = 15
Answer:
1.15 hr
Step-by-step explanation:
Given that:
To get bike fixed :
Speed = 3 miles per hour
Distance = 1.5 miles
Time taken = distance / speed
Time taken = 1.5 / 3 = 0.5 hour
Waiting time for repair = 30 minutes = 0.5 hours
Return home :
Speed = 10 miles per hour
Distance = 1.5 miles
Time taken = distance / speed
Time taken = 1.5 / 10 = 0.15 hour
Total time : (0.5 + 0.5 + 0.15) = 1.15 hr
