Answer:
x = 10
Step-by-step explanation:
The total measures of a circle must add up to 360°. In the diagram given there are two angles that are not given, however, both of these should be equal to each other. That means that the sum of the other two angles ('5x - 5' and 93°) must be equal to the other angle of the same measure (138°):
5x - 5 + 93 = 138
Combine like terms: 5x + 88 = 138
Subtract 88 from both sides: 5x + 88 - 88 = 138 - 88 or 5x = 50
Divide by 5: 5x/5 = 50/5 or x = 10
Answer:
x = 6 and x = -6
Step-by-step explanation:
Answer: <em>A. 241 feet</em>
Step-by-step explanation:
<em>The figure shows two rectangular triangles.
</em>
<em>These triangles are similar since they have two identical angles:
</em>
<em>the first angle is 90 degrees;
</em>
<em>the second angle is equal because the law of reflection states that the angle of incidence is equal to the angle of reflection.
</em>
<em>The law of reflection states that the angle of incidence is equal to the angle of REFLECTION.</em>
<em>Let's make the proportion:</em>

<em>It takes a minimum of 100 feet for a parachute to open and safely land without injury, so:</em>
<em>341.25 - 100 = 241.25 (feet)</em>
<em>241.25 ≈ 241 (feet)</em>
