Let another angle be x

According to angle sum property

$\\ \rm\Rrightarrow x+35+78=180$

$\\ \rm\Rrightarrow x+113=180$

$\\ \rm\Rrightarrow x=180-113$

$\\ \rm\Rrightarrow x=67°$

67°, every triangle equals 180° so add together 35+78 which equals 113. subtract 180-113 and get 67!

A small box weighs 1 25 pounds. A large box weighs 3 1/3 time as much as the small box. how much does the large box weigh?

egoroff_w [7]

Answer:

416.7pounds

Step-by-step explanation:

Given parameters:

Weight of the small box = 125pounds

Unknown:

Weight of the larger box = ?

Solution:

The large box weighs $3\frac{1}{3}$ times as the small box:

So;

= 125pounds x $\frac{10}{3}$

= 416.7pounds

The sector of a circle with a 60 millimeters radius has a central angle measure of 30° . What is the exact area of the sector in

ASHA 777 [7]

R = 60
60^2 * pi = 3600 * pi
angle = 30°
3600pi / 30 = 120pi
the answer is 120 * pi

Jaden is flying a kite with an angle of elevation of 33 degrees. If Jaden lets out 275 feet of string, how high above the ground

pshichka [43]

Answer:

149.8 feet

Step-by-step explanation:

θ = Angle of elevation = 33°

The length of string Jaden lets out = Hypotenuse = 275 feet.

How high above the ground that the kite is flying = Opposite Side.

We are solving this question using the Trigonometric function of Sine

Sin θ = Opposite Side/Hypotenuse

Sin 33 = Opposite/275 feet

Cross Multiply

Sin 33 × 275 feet = Opposite

Opposite side(Height ) = 149.77573463 feet

Approximately to the nearest tenth = 149.8 feet

Evaluate the variable expression when a=-4, b=2, c=-3, and d =4. b-3a/bc^2-d

gtnhenbr [62]

Answer:

Therefore, the variable expression when a=-4, b=2, c=-3, and d =4 is

$\dfrac{b-3a}{bc^{2}-d}=1$

Step-by-step explanation:

Evaluate:

$\dfrac{b-3a}{bc^{2}-d}$

When a=-4, b=2, c=-3, and d =4

Solution:

Substitute, a=-4, b=2, c=-3, and d =4 in above expression we get

$\dfrac{b-3a}{bc^{2}-d}=\dfrac{2-3(-4)}{2(-3)^{2}-4}\\\\=\dfrac{2+12}{18-4}\\\\$

$\dfrac{b-3a}{bc^{2}-d}=\dfrac{14}{14}=1$

Therefore, the variable expression when a=-4, b=2, c=-3, and d =4 is

$\dfrac{b-3a}{bc^{2}-d}=1$
