What is the measure of angle c? (Brainliest and Bonus points for best answer)
k0ka [10]

Answer:

\displaystyle 65°

Step-by-step explanation:

Angle <em>b</em> and 135° form a <em>linear pair</em>, so when summing them up to 180°, you will have 45° left over:

\displaystyle 180° = 135° + m∠b; 45° = m∠b

Now, by the <em>Vertical</em><em> </em><em>Angles</em><em> </em><em>Theorem</em>, angle <em>a</em> and 70°, in this case, are to be in <u>congruence</u> with each other, so you have that.

Now you must find the the measure of angle <em>c</em> sinse you have already found the measure of two angles already:

\displaystyle 180° = 45° + m∠c + 70° → 180° = 115° + m∠c; 65° = m∠c

I am joyous to assist you at any time.

Answer:

<h2>             18.3</h2>

Step-by-step explanation:

from cosines theorem:

t² = 11² + 14² - 2•11•14•cos87°

t² = 121 + 196 + 308•0.05236

t² = 333.12688

t = √333.12688

t = 18.2517... ≈ 18.3

S_A_V [24]
0.75x + 0.5y = 25.....and she doesn't want any licorice....so x = 0
0.75(0) + 0.5y = 25
0.5y = 25
y = 25/0.5
y = 50....she can get 50 cherry candies
