Let the number be n

$\\ \sf\longmapsto 2(n+10)=60$

$\\ \sf\longmapsto n+10=60/2$

$\\ \sf\longmapsto n+10=30$

$\\ \sf\longmapsto n=30-10$

Instructions: Find the missing side. Round your answer to the nearest

ch4aika [34]

Answer:

Step-by-step explanation:

Tan(51) = opposite / adjacent

The adjacent side makes up the reference angle (51o)

The opposite side is not part of the reference angle

adjacent side = x

opposite side = 16

Tan(51) = 16 / x Multiply both sides by x

x * Tan(51) = 16 Divide by tan 51

x = 16 / tan(51)

tan(51) = 1.2349

x = 16 / 1.2349

x = 12.96

Help me I don’t get this

andre [41]

Step-by-step explanation:

Area = 8 × 5

Area = 40^2

Perimeter is the length around the edges

Therefore it is 8+8+5×5 (since there are 4 edges)

Perimeter = 2×8 + 2×5

= 40 + 10

= 50cm
