Will give brainliest! How many distinct triangles can be made? I think I have to first find the measure of length b and then com
Anarel [89]
Check the picture below.

this is a case of the ambiguous case with an SSA, AC and CB are the sides and the angle is at A.

the ambiguous case has two triangles, the case when B is acute, CB sticks out, and the case when B is obtuse, CB sticks inside, it just so happen that those two angles for B are "supplementary" angles.

if you check the sin⁻¹ of that, we'll get the acute version of B, that's because of the constraints on the range of the inverse sine function, and we get ∡B ≈ 36.86989765°.

and of course, the other angle for B will be 180 - 36.86989765.

A recipe for crumb cake says to mix 3/8 cup of brown sugar and 1/3 cup of white sugar. From this sugar mixture, set aside 1/4 cu
ch4aika [34]

brown sugar= \frac{3}{8}

white sugar= \frac{1}{3}

you need to mix brown sugar with white sugar

\frac{3}{8} + \frac{1}{3} = \frac{9+8}{24} = \frac{17}{24}

then it says you need to set aside 1/4 for the crumb topping from the previous sugar mixture that was  \frac{17}{24}, so

\frac{17}{24} - \frac{1}{4} = \frac{68-24}{96} = \frac{11}{24}

The sugar mixture used to make the cake is \frac{11}{24}

Wilbur landed his plane, causing it to descend at a rate of 0.2 kilometers per minute. He reached the ground after 15 minutes
Brrunno [24]

Answer: If the plane descends at the rate of 0.2 km per minute and landed after 15 mins, that means the plane started at 3 km elevation when it started to descend (t=0). The table is then constructed using the intialn values.

10 POINTS SOMEONE PLEASEE HELP
d1i1m1o1n [39]

Answer:

x = 18.5

∠1 = 76°

∠2 = 104°

∠3 = 76°

∠4 = 104°

∠5 = 76°

∠6 = 104°

Step-by-step explanation:

4x + 2 + 6x - 7 = 180

4x + 6x = 180 - 2 + 7

10x = 185

x = 185/10

x = 18.5

∠1 = 76°

∠2 = 104°

∠3 = 76°

∠4 = 104°

∠5 = 76°

∠6 = 104°
