Given that A=25deg, B=43deg, and c=17deg solve triangle ABC

1 answer:

8 0

This is a situation known as AAA (angle, angle, angle)

Knowing three angles only determines the triangle up to similarity.

If we don't know at least one length, we're not going to be able to find any lengths.

Answer:

Step-by-step explanation:

a. This is a right triangle with two sides and one angle given.

-We apply Sine Rule to find the angle B:

$\frac{a}{Sin \ A}=\frac{b}{Sin \ B}=\frac{b}{Sin \ C}$

-The sides given are 10and 17 and the right angle 90°

$\frac{17}{Sin \ 90 \textdegree}=\frac{10}{Sin \ m\angle B}\\\\m\angle B=Sin^{-1}\frac{10}{(17/Sin \ 90\textdegree)}\\\\=36.03\textdegree$

Hence the angle B is 36.03°

b.We again use the sine rule to obtain the unknown angle w:

-15 corresponds to 90° and 9 corresponds to w°

$\frac{a}{Sin \ a}=\frac{b}{Sin \ B}\\\\\frac{15}{Sin \ 90\textdegree}=\frac{9}{Sin \ w\textdegree}\\\\\\\\w=Sin^{-1}(\frac{9}{15}), \ \ Sin \ 90\textdegree=1\\\\=36.87\textdegree$

Hence, the measure of w is 36.87°

Divide 88,800 By 100 Explain the shift of the digits and the change in the value of each digit

ololo11 [35]

88,800÷100=888 because when you are dividing by multiples of 10, the place value always move over to the right depending on how many digits there are.
