The unknown exponent is 5
0.50 because the 8 is in the hundredth place and is greater than 5 so you round it up. Then you turn that to a zero because the 8 becomes a 10 but you only use the zero. Then you turn the 4 to a 5 or else the number would be getting smaller and not larger.
That's a 2/6 probability, so 1/3 -- B.
Answer: 6.6ft
Step-by-step explanation:
Explanation:
Draw altitude AD to segment BC such that point D is on BC. This creates right triangles ADB and ADC.
Hypotenuses AB and AC are given as congruent. Leg AD in each triangle is congruent to itself by the reflexive property of congruence.
Then the triangles ADB and ADC are congruent by the HL congruence theorem.
Angles B and C are corresponding parts of congruent triangles, so are congruent by CPCTC.
