<h3>Sin $\theta_{1}=\frac{3\sqrt{21}}{17}$ </h3>

Solution given:

Cos $\theta_{1}=\frac{10}{17}$

$\frac{adjacent}{hypotenuse}=\frac{10}{17}$

equating corresponding value

we get

adjacent=10

hypotenuse=17

perpendicular=x

now

by using Pythagoras law

Hypotenuse ²=perpendicular²+adjacent ²

substituting value

17²=x²+10²

17²-10²=x²

x²=17²-10²

x²=189

doing square root

$\sqrt{x²}=\sqrt{189}$

x= $3\sqrt{21}$

now

In I Quadrant sin angle is positive

Sin $\theta_{1}=\frac{perpendicular}{hypotenuse}$

How do you rewrite an equation by completing the square?<br> x^2+10x+21=0

AleksAgata [21]

Answer:

Step-by-step explanation:

x²+10x+21=0

x²+10x+(10/2)²-(10/2)²+21=0

x²+10x+25-25+21=0

(x+5)²-4=0

(x+5)²=4

(x+y)²=(x+y)(x+y)=x(x+y)+y(x+y)=x²+xy+xy+y²=x²+2xy+y²

(x+y)²=x²+2xy+y²

coefficient of x=2y

y²=[(coefficient of x)/2]²=(2y/2)²=y²
