The lateral area is π r ℓ units²
<span>The base is 20 feet across so the radius is 10 feet </span>
<span>Multiply 3.14 × 10 × 14 </span>
<span>3.14 × 10 = 31.4 </span>
<span>31.4 × 14 = 31.4 × 10 + 31.4 × 4 </span>
<span>= 314 + 120 + 4 + 1.6 </span>
<span>= 434 + 5.6 </span>
<span>= 439.6</span>

Answer:
1. is a 30 60 90 triangle so x = 30
pardon my bad handwriting for below
2.
STEP 1: subtract the angle you have from 180
STEP 2: add your x values together, if there is a non x number (such as + 10) balance it out on the other side by adding or subtracting
STEP 3: divide so that x has no coeffecient in front of it
STEP 4: substitute x values with the value you got
STEP 5: verify by adding the angles you got, it'll be correct if it equals 180
