Answer:
Answer: 51.3∘ and 128.7∘
Step-by-step explanation:
In ΔUVW, w = 5.3 inches, v = 3.6 inches and ∠V=32°. Find all possible values of ∠W, to the nearest 10th of a degree.
We solve the above question using sine rule formula. This is given as:
w/sin W = v/sin V
w = 5.3 inches
v = 3.6 inches
∠V=32°.
5.3/sin W = 3.6/sin 32
Cross Multiply
sin W × 3.6 = 5.5 × sin 32
sin W = 5.5 × sin 32/3.6
W = arc sin (5.5 × sin 32/3.6)
W = 51.28° or 128.72°
Approximately
= 51.3° or 128.7°
Answer:
Its 7
Step-by-step explanation:
when x is 18 y is 6. 18 divided by 6 is 3.
so x is 21 divided by 3 is 7.
Hope it helpsssss !!!!!!!
B - 16 m2
solve:
(pi)x2^2=12.6
(pi)x3^2=28.3
28.3-12.6=15.7
round to 16
Answer:
5 cm
Step-by-step explanation:
Let the shorter side be a, longer side be b, hypotenuse be c
By Pythagorean theorem:
a² + b² = c²
a² + (a + 7)² = (a + 8)²
a² + a² + 14a + 49 = a² + 16a + 64
a² - 2a - 15 = 0
a² + 3a - 5a - 15 = 0
a(a + 3) - 5(a + 3) = 0
(a + 3)(a - 5) = 0
a = -3 or a = 5
Because a is a side length and is a positive number
a = 5
