Each bag contains 50 pattern blocks so 4 bags is
50 x 4 = 200 pattern blocks
hope this helps
10,000-1,000=9,000 -100
8,900,i think maybe
(7) m∠A = 52°
(8) m∠B = 117°
Solution:
(7) Let us first define the supplementary and complementary angles.
Supplementary angles: Two angles are said to be supplementary angles if their sum is add up to 180°
Complementary angles: Two angles are said to be complementary angles if their sum is add up to 90°
Given supplement of 142° = 180° – 142°
= 38°
Complement of ∠A = Supplement of 142°
⇒ Complement of ∠A = 38°
Measure of ∠A = 90° – 38°
= 52°
Hence m∠A = 52°.
(8) Given complement of 27° = 90° – 27°
= 63°
Supplement of ∠B = Complement of 27°
⇒ Supplement of ∠B = 63°
Measure of ∠B = 180° – 63°
= 117°
Hence m∠B = 117°.
Answer:
5x +11y +10
Step-by-step explanation:
7x+11y+9-2x+1
Combine like terms
7x-2x + 11y +9 +1
5x +11y +10
