HELP PLSSS CAN SOMEONE SOLVE THIS

Step-by-step explanation:

we use the law of sine :

a/sin(A) = b/sin(B) = c/sin(C)

a, b, c being the sides, A, B, C being the opposing angles of the sides.

and remember, the sum of all angles in a triangle is 180°.

so,

JL/sin(90) = KL/sin(72)

JL/1 = KL/sin(72)

KL = JL × sin(72) = 10 × 0.951056516... =

= 9.51056516... ≈ 10

JK/sin(L) = JL/sin(90) = JL

JK = JL × sin(L)

angle L = 180 - 90 - 72 = 18°

JK = JL × sin(18) = 10 × 0.309016994... =

= 3.09016994... ≈ 3

The sum of a number times 7 and 21 is at least 29. Write as an inequality

PtichkaEL [24]

The inequality is 7x + 21 $\leq 29$

Step-by-step explanation:

DATA:

Let the number be x

Number times 7 = 7*x

Sum of a number times 7 and 21 = 7x + 21

Is at least 29

INEQUALITY:

7x + 21 $\leq 29$

SOLVE:

7x $\leq 29-21$

7x $\leq 8$

x $\leq \frac{8}{7}$

Therefore, the inequality is 7x + 21 $\leq 29$
