Part 3) <span>Given triangle XYZ as shown at right find YZ rounded to the nearest tenth
we know that
</span><span>the sum of the internal angles of a triangle add up to 180 degrees
</span>so
m∠X=180-[55+29]----> 96°
applying the law of sines
YZ/sin X=35/sin 55°------> YZ=35*sin 96/sin 55-----> YZ=42.49
YZ=42.5 units
the answer Part 3) isYZ=42.5 unitsPart 4)
we know that
OQ/NQ=PR/NR
NQ=4X+(2X+2)---> 6X+2
OQ=2X+2
PR=15
NR=24+15----> 39
(2X+2)/(6X+2)=15/39
39*(2X+2)=15*(6X+2)
78X+78=90X+30
90X-78X=78-30
12X=48
X=4
The answer part 4) isx=4Part 5) A trapezoid is show below. Calculate the measure of angle x. Round to the nearest tenth of a degree
see the picture with letters attached to better understand the problem
we know that
BC=36-28-----> 8 ft
sin x=BC/AC-----> sin x=8/12
x=arc sin(8/12)-------> x=41.81°------> x=41.8°
the answer Part 5) isx=41.8°
Answer:
3 ft
Step-by-step explanation:
Ladder = 12 ft
Distance between base of the ladder and the building = 5 ft
a² + b² = c²
a² + 5² = 12²
a² = 12² - 5²
a² = 144 - 25
a² = 119
a = √119
a = 3.3 ft
a = 3 ft (nearest ft)
Answer:
Step-by-step explanation:
The mixed number 1 1/3 is equal to the improper fraction 4/3.
The conclusion of this problem was in fact 9, from all the information that was given that is the only viable answer
