Sidetriangle

>> This is your Math Gal Julie Harland. Please visit my website at YourMathGal.com where all of my videos are organized by topic. All right. We're going to solve this word...

- WELCOME TO EXAMPLES OF USING A TRIG EQUATION TO DETERMINE THE MEASURE OF AN ANGLE IN A RIGHT TRIANGLE. SO IN THIS DIAGRAM HERE WE WANT TO DETERMINE THE MEASURE OF ANGLE THETA. LET'S START BY...

- WE'RE GIVEN TRIANGLE BIG IS SIMILAR TO TRIANGLE MOP. WE WANT TO FIND V HERE, WHICH IS THE LENGTH OF SIDE BI. IN SIMILAR TRIANGLES, THE RATIOS OF CORRESPONDING SIDES ARE PROPORTIONAL, WHICH...

- IN THESE EXAMPLES WE WANT TO USE A TRIG EQUATION TO DETERMINE THE LENGTH OF A SIDE OF A RIGHT TRIANGLE. SO LOOKING AT OUR DIAGRAM HERE, IF WE USE THE ANGLE THAT MEASURES 34 DEGREES, THIS SIDE OF THE...

- WE WANT TO SOLVE THE RIGHT TRIANGLE GIVEN THE LENGTH OF SIDE B IS EIGHT UNITS, AND THE MEASURE OF ANGLE B IS 38 DEGREES. SO IF ANGLE B IS 38 DEGREES, SIDE B IS OPPOSITE THIS ANGLE, TO THIS WOULD BE...

- WE WANT TO FIND THE EXACT TRIG FUNCTION VALUES USING THE RIGHT TRIANGLE. BECAUSE WE WANT TO FIND ALL SIX TRIG FUNCTION VALUES, WE NEED THE LENGTH OF ALL THREE SIDES OF A TRIANGLE. NOTICE HOW...

- IN THIS EXAMPLE, WE WANT TO DETERMINE THE EXACT TRIG FUNCTION VALUES FOR 1, 470 DEGREES, AND THERE ARE TWO MAIN WAYS OF DOING THIS. WE CAN USE A UNIT CIRCLE OR WE CAN USE REFERENCE TRIANGLES. FOR...

- WE WANT TO SOLVE THIS TRIANGLE GIVEN THE LENGTH OF ONE OF THE SIDES AND THE MEASURE OF TWO OF THE ANGLES. TO KEEP THINGS ORGANIZED, LET'S GO AHEAD AND LABEL THE VERTICES AND THE SIDES. SO...

This video is provided as supplementary material for courses taught at Howard Community College and in this video I'm going to talk about the side splitter theorem. I'll explain what...

- WE WANT TO FIND THE EXACT TRIG FUNCTION VALUES USING REFERENCE TRIANGLES. NOTICE HOW THE ANGLES WERE GIVEN IN RADIANS, SO WE COULD CONVERT THESE TO DEGREES. BUT I THINK IT'S IMPORTANT TO...
