Answer:

m<CDE=66 degrees.

Step-by-step explanation:

(1) Extend the segment DC so it intersects with line BA. Call the intersection F.

(2) Consider triangle BCF. In here, we are given m<ABC=24 deg. Since m<BCD = 90 deg, we known that m<BCF = 90 deg. Knowing two angles in the triangle BCF lets us determine the rhird angle m<BFC = 180-90-24 = 66 deg.

(3) Because of the fact that AB || DE and the fact that line DF intersects AB and DE, the angles <BFC and <CDE are congruent. Therefore m<CDE=66 deg.

What is the product of (7 x 10^-5) x (5 x 10^-8) (7 x 10^-5) x (5 x 10^-8) = ? x 10^?

arsen [322]

Answer:

$3.5\times10^-^1^2$

Step-by-step explanation:

$(7 \times 10^-5) \times (5 \times 10^-8)$

Evaluate

$(7 \times 5)\times(10^-^5\times10^-^8)$

$35\times10^-^5^-^8$

$35\times10^-^1^3$

$35\times10^1\times10^-^1^3$

$3.5\times10^1^-^1^3$

$3.5\times10^-^1^2$

Thus, the answer is $3.5\times10^-^1^2$
