As you can probably tell, this is a 30, 60, 90 triangle. That means the degree measures are 30, 60, and 90. These are special triangles. For every 30, 60, 90 triangle in the world, the shorter leg (in your case, x) is ALWAYS two times shorter than the hypotenuse (6). 6/2=3, so x=3. Also, the longer leg for a 30, 60, 90 triangle is always equal to the shorter leg times the square root of 3. So, 3 times the square root of 3 is about 5.2. So, y=5.2. Hope it helps!
Answer:
Her average speed was 48..88 mph
Step-by-step explanation:
Use a rule of 3 to find the time she traveled at 60 mph:
60 miles ----------1 hour
40 miles ---------- x
60x = 40
x = 40/60 = 0.67 hours
She traveled 40+50= 90 miles
During 1.25+0.67= 1.92 hours
90/1.92 = 48.88 mph

Answer:
64x^2/3x^5/4
Step-by-step explanation:
(4x^2/3)^3 / (81x^5)^1/4
4^3*x^2/3*3 / 3^4*1/4*x^5/4
64*x^2 / 3*x^5/4
