Answer:

53°

Step-by-step explanation:

Because a triangle is equal to 180°, we subtract the 84° and 43° from the 180° and get the measure of the third angle: 53°

The number 137.5 is 125% of what number

murzikaleks [220]

125% of x =137,5

125/100 * x= 137.5

5/4 *x=137,5

5x/4= 137,5

x=4*137,5/5

x=4*27,5

x=110

In right triangle ABC, mC - 90° and AC BC. Which trigonometric ratio is cquivalent to sin b?

vaieri [72.5K]

Answer:

All trigonometric Ratios are $SinB = \frac{AC}{AB}$ , $SinA= \frac{CB}{AB}$ , $CosA= \frac{AC}{AB}$

And $Cos B = \frac{CB}{AB}$ .

Step-by-step explanation:

Given that,

A right angle triangle ΔABC, ∠C =90°.

Diagram of the given scenario shown below,

In triangle ΔABC :-

$Hypotenuse = AB\\Base = CB\\Perpendicular = AC$

So, $Sin\theta = \frac{perpendicular}{hypotenuse}$

$SinB = \frac{AC}{AB}$

Now, for ∠A the dimensions of trigonometric ratios will be changed.

Here the base for ∠A is AC , perpendicular side is CB and hypotenuse will be same for all ratios.

$SinA= \frac{CB}{AB}$

Again, $Cos\theta= \frac{base}{hypotenuse}$

Then, $CosA= \frac{AC}{AB}$

And $Cos B = \frac{CB}{AB}$ .

Hence,

All trigonometric Ratios are $SinB = \frac{AC}{AB}$ , $SinA= \frac{CB}{AB}$ , $CosA= \frac{AC}{AB}$

And $Cos B = \frac{CB}{AB}$ .

A bakery uses 3/10 of a cup of flour in one batch of biscuits. The bakery uses 3/5 of a cup yesterday. how many batches of biscu

jarptica [38.1K]

Answer: The bakery made 3 batches of biscuits.

Step-by-step explanation:

To find how many batches the bakery made set up a proportional relationship .

so if $\frac{3}{10}$ can make 1 batch of biscuit

is asking how many batch of biscuits can $\frac{3}{5}$ cup of flour make

so solve this divide 3/5 by 3/10 to find the number of batches

$\frac{3}{5} /\frac{3}{10}$ = $\frac{30}{15 }$ = 2 +1
