Answer: # 4.) 9.4
#5.) 10.2 cm
#6.) 5 inches .
Step-by-step explanation: Assuming that a right triangle is expected, use the <u><em>Pythagorean Theorem</em></u> to calculate the third side: a² + b² = c²
Then take the square root of 89. A calculator is handy for most of these!
√89 = 9.433981 . Round to 9.4
√104 = 10.1980 Round to 10.2 <u>Remember to include the units, cm in the answer.</u>
<u>Memorize this one:</u>
<u>Given side lengths of 3 & 4, the hypotenuse is 5!</u>
3² + 4² = 5² Called a "Pythagorean Triple"
9 + 16 = 25
The square on the hypotenuse is a perfect square of 5
No calculator necessary, and you are likely to see this ratio in other questions.

Let’s say the side BC is extended till D
1) measure of angle ACD = 105° ( angle ACD is exterior angle)
45 + 60 = 105
2) I found the answer by adding the values of Angle A and Angle B or by using the exterior angle property.
3) I observed that exterior angle property can be used here. Exterior angle property is that an exterior angle of a triangle is equal to the sum of the opposite interior angles.
D=56
b=56
a=57
c=124
e=28
f=28
Answer:
14
Explanation:
The given triangle is a right-angled triangle. This means that special trig functions can be applied.
These functions are as follows:
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
Now, we have:
θ = 40°
opposite = 12 m
adjacent is the distance we want to find
Substitute with the givens in the tan formula to get the distance as follows:
tan (40) = 12 / distance
distance = 12 / tan (40)
distance = 14.3 which is approximately 14 m
Hope this helps :)
