Step-by-step explanation:
1. k = 76°
2. r = 25cm
3. as the drawing attached
one pair of parallel lines : AB and DC
one pair of equal angles : <em>L</em><em> </em>A and <em>L</em><em> </em>D
4. (7²× 3`¹)⁴×7^5 / (3² × 7^(-6))³
= (7^8 × 3`⁴)×7^5/ (3² × 7^(-6))³
= (7^13 × 3`⁴)/ (3^6 × 7^(-18))
= (7^(31) × 3^(-10))
= 7^31 / 3^10
Answer:
1
Step-by-step explanation:
By PEDMAS, do multiply & division first, then do subtraction
21 ÷ 7 * 3 - 4 * 2
= (21 ÷ 7 * 3) - (4 * 2)
= (3 * 3) - (8)
= 9 - 8
= 1
