Answer:
A)
Step-by-step explanation:
Pattern of upper half: 1, 3, 6, 3, 1
Pattern of lower half: 1, 1, 1, 3, 5
Repeat the patterns:
1, 3, 6, 3, 1, 1, 3, 6, 3, 1
1, 1, 1, 3, 5, 1, 1, 1, 3, 5
Answer: A)
25+3=28
-3
x=36
First rewrite equation then multiply each side by 36. 9x-36=4x+144.
then move the variable 9x-4x+36=144. Next subtract 9x and 4x ...5x=144+36.... 5x=180. Lastly you divide 180÷5 this your answer x=36
t= .43
8t + 3 -t
8t - t = 7t
7t + 3
7t/7 = t
3/7 = .43
The measure of angle A is 55°.
Solution:
Let us take B be the adjacent angle of 145°.
<em>Sum of the adjacent angles in a straight line = 180°</em>
⇒ m∠B + 145° = 180°
Subtract 145° from both sides.
⇒ m∠B + 145° - 145° = 180° - 145°
⇒ m∠B = 35°
The adjacent angle of 145° is 35°.
In the image, angle B and angle A equal to 90°.
⇒ m∠B + m∠A = 90°
⇒ 35° + m∠A = 90°
Subtract 35° from both sides.
⇒ m∠A = 55°
