i. Let t be the line tangent at point J. We know that a tangent line at a point on a circle, is perpendicular to the diameter comprising that certain point.

So t is perpendicular to JL

let l be the tangent line through L. Then l is perpendicular to JL

ii. So t and l are 2 different lines, both perpendicular to line JL.

2 lines perpendicular to a third line, are parallel to each other, so the tangents t and l are parallel to each other.

Remark. Draw a picture to check the steps

JL is a diameter of circle K. If tangents to circle K are constructed through points L and J, then the two tangents will be parallel because the tangent at a point on a circle is perpendicular to the diameter.

two blocks of wood are shaped as right rectangle prisms the smaller block has a length of 9 cm a width of 3 cm and a height of 7

dolphi86 [110]

Answer:

1,512 cm³

Step-by-step explanation:

The general formula for the volume of a prism is:

V= Bh, where B = the area of the base and h = height of the prism

Given the dimensions of the smaller block as 9cm x 3cm x 7cm, then the dimensions of the larger block (double the dimensions of the smaller block) must be 18cm x 6cm x 14cm. Using these measurements:

V = (18)(6)(14) = 1,512 cm³

In parallelogram LMNO, what is the measure of angle N? 50° 70° 110° 130°

belka [17]

we know that

In a parallelogram opposite angles are congruent and consecutive angles are supplementary.

m∠O=m∠M

m∠L=m∠N

m∠O+m∠L= $180$
