It’s an isoceles triangle so 180-64=116degrees = the sum of the other two equal angles in the triangle QRP and so angle QRP is 116÷2=58degrees, angles QRP and SRT are vertically opposite so they’re equal. The triangle SRT is also isosceles so 180-58= 122degrees = the sum of the last two equal base angles (including RST that you want to find) So lastly do 122÷2= 61degrees = angle RST

2 5/7+4 3/5= help please

Ainat [17]

Answer:

$7\frac{11}{35}$

Step-by-step explanation:

$2\frac{5}{7}+4\frac{3}{5}$

add the whole numbers

$2+4=6$

combine the fractions

$\frac{5}{7}+\frac{3}{5}$

LCM is 35 because 7 * 5 =35

$\frac{5}{7}=\frac{5\cdot \:5}{7\cdot \:5}=\frac{25}{35}$

$\frac{3}{5}=\frac{3\cdot \:7}{5\cdot \:7}=\frac{21}{35}$

$\frac{25}{35}+\frac{21}{35}=\frac{25+21}{35}$

$=\frac{46}{35}$

change the improper fraction into mixed number

$6+1\frac{11}{35}$

$=7\frac{11}{35}$
