Answer:
133,371
Step-by-step explanation:
b times h divided by 2
522 x 511 x 1/2 = 133,371
Answer:
for it i think it would be 66
Step-by-step explanation:
We solve the equation, ( a + a + 1 )^2 = 112 + a^2 + ( a + 1 )^2;
Then, ( 2a + 1 )^2 = 112 + a^2 + a^2 + 2a +1;
4a^2 + 4a + 1 = 113 + 2a^2 + 2a;
Finally, 2a^2 + 2a - 112 = 0;
a^2 + a - 56 = 0;
We use <span>Quadratic Formula for this Quadratic Equation;
The solutions are a1 = 7 and a2 = -8;
But a is a natural number; so, a = 7;
The natural consecutive numbers are 7 and 8.</span>
Part 3 and four have the same place
ans: 70 ...( it is by ; 180-110) because of straight angle= 180...........
