• Q1

What is the appropriate equation to solve for the third side in the given figure?

$c=\sqrt\left\{15^2+18^2-2\left\left(15\right\right)\left\left(18\right\right)\cos65^o\right\}$

$c=15\sin65^o$

$c=18\sin65^o$

$c=\sqrt\left\{15^2+18^2+2\left\left(15\right\right)\left\left(18\right\right)\cos65^o\right\}$

• Q4

One of the teachers in Sto. Niño National High School conducted a home visitation of a student who is no longer participating in learning activities. Having some modules at hand, he needed to drop by the school first. The distance from the teacher's house (T) to school (S) is 40 m and school (S) is 25 m away from the learner's house (L). From the figure, the angle between the segment connecting the learner's house to teacher's house and segment connecting the learner's house to the school is 50o

Question: How far is the teacher's house from the learner's house?
