In △ABC, m∠A=52°, c=11, and m∠B=19°. Find a to the nearest tenth.

Ugo [173]

From the problem we have

In △ABC, m∠A=52°, c=11, and m∠B=19°.

Draw the diagram with the help of given information, (see the attached image)

Now using Sine Law in the Triangle ABC, we can write

Now from Triangle ABC , we can write

$\frac{a}{sin52}=\frac{11}{sin109} \\$

Now simplify , we get

$\Rightarrow a=\frac{11}{sin109}*sin52\\ \\ \Rightarrow a=\frac{11}{0.9455}*0.7880\\ \\ \Rightarrow a=9.1676 \approx 9.2\\$

Harry and Terry are each told to calculate 8−(2 5). Harry gets the correct answer. Terry ignores the parentheses and calculates

KIM [24]

There is a sign missing, but I think it's a "+" like this:

8-(2+5)

H, ,that is Harry's answer would be:

first the bracket:

8-(7)

and then the whole expression:
8-(7)=1, so H=1

Terry's answer would be:

8-2+5, which we do from left to right:

6+5=11, so T=11

then H-T is 1-11, which is -10.
