Find the measure of angle A. 66° x +49 x+83

liubo4ka [24]

Step-by-step explanation:

Since , internal sum of angle of triangle is 180°

So,

66 + x +49 + x+83 = 180

or, 198 + 2x = 180

or, 2x = 180 -198

or, 2x = -18

hence, x = - 9

Now angle A = x + 49

= (-9) + 49

= 40

Hence measure of angle A is 40°.

-u≥4−u≥4 true. Then write an equalivalent inequality, in terms of uu. (Numbers written in order from least to greatest going acr

ziro4ka [17]

Answer:

$(a)\ u \le -4$

$(b)\ u =\{-\infty,.....,-6,-5,-4\}$

Step-by-step explanation:

Given

$-u \ge 4$

Solving (a): An equivalent inequality

We have:

$-u \ge 4$

Multiply both sides by -1 (this changes the inequality)

$-u*-1 \le 4 * -1$

$u \le -4$

Solving (b): Values of u from least to greatest

$u \le -4$ implies that u ends at -4, starting from negative infinity

So, the list is:

$u =\{-\infty,.....,-6,-5,-4\}$
