Two sides and an angle (SSA) of a triangle are given. Determine whether the given measurements produce one triangle, two tria

Nataliya [291]

<h2>These measurements will not form a triangle.</h2>

Step-by-step explanation:

We have sine formula

$\frac{a}{sinA}=\frac{b}{sinB}=\frac{c}{sinC}$

Given

a = 9.7

b = 49

A = 26°

Substituting

$\frac{a}{sinA}=\frac{b}{sinB}=\frac{c}{sinC}\\\\\frac{9.7}{sin26}=\frac{49}{sinB}\\\\sinB=2.21$

Value of sin B is greater than 1, which is not possible.

Hence these measurements will not form a triangle.

A swimming pool had 2.5 million liters of water in it. Some water evaporated, and then the pool only had 2million liters of wate

First you would subtract 2.5 by 2 and you get .5. Next you would find the percentage of .5 out of 2.5, you would then get 0.0125%

Which of the following equations are equivalent to-2m-5m-8 #-(-7) + m?D-15m-4md:7m-8-rn-4□-3m-8-4-m□m-4.7m-8-8.7m- 4-m□-8.3m-4-m

Readme [11.4K]

-2m - 5m - 8 = 3 + (-7) + m
-7m - 8 = 3 - 7 + m
-7m - 8 = m - 4 <=== here is one

m - 4 = -7m - 8 <=== another one
-8 - 7m = -4 + m <== and another one
