Answer:
70
Step-by-step explanation:
2x(3x5)=15 15x0.5=7.5 7.5+7.5=15
2x(5x11)=55
55+15=70
All right angle triangles have a 90 degree angle. 90+42=132
All triangles have angles that add up to 180 degrees 180-132=48
90+42=132
180-132=48
<span>The missing angle is 48°</span>
We are asked to evaluate the given expression 3 (r² + t) - r² given that r is equivalent to 2 and t is equivalent to 7. The solution to this problem is shown below:
3 (r² + t) - r² , substitute r=2 and t=7 in the expression
3 (2² + 7) - 2² , perform squared
3 (4+7) -4, perform addition of 4 and 7
3 (11) -4, perform multiplication os 3 and 11
33 - 4, perform subtraction
29
The answer is 29.
It's the same thing, the different is depends in which side was x
