Yes. Find a common denominator between 2/8 and 1/5. 2/8 simplifies to 1/4, so we're going to instead find the least common denominator between 1/5 and 1/4. The least common multiple of 4 and 5 is 20. In order to change 1/5 to something / 20, we need to multiply both the numerator and denominator by 4: 4/20. For 1/4, we need to multiply both the numerator and denominator by 5: 5/20. So, 1/4 (2/8) is greater than 1/5.
Answer:
x=-3,x=9
Step-by-step explanation:
x^2-6x-20-7=0
x^2-6x-27=0
x^2-(9-3)x-27=0
x^2-9x+3x-27=0
x(x-9)+3(x-9)=0
(x+3)(x-9)=0
x=-3,x=9
Answer:
39 degrees
Step-by-step explanation:
The sum of angle in the triangle ABC is a80 degrees
m<ACB + <BAC + <ABC =1 80
90 + <BAC + 51 = 180
141 + m<BAC = 180
m<BAC = 180-141
m<BAC = 39 degrees
Hence the measure of m<BAC is 39 degrees
Answer:
the answer is 90
Step-by-step explanation:
296-96=90
Since we have the triangle, but don't know which side 4 is on, we have one where x is opposite a 50 degree angle (they are the same if across either 50 degree side) and another across the 80 degree one. In addition, it's really ratios and sin/cos/tan from there!
