The answer is (C) because from 1976 - 1978 there was a bit deflation
Answer:
Converse: False
Inverse: False
Contrapositive: True
Step-by-step explanation:
Converse: Two angles can be any degree and be congruent, they do not have to both be right angles, which makes this statement false.
Inverse: Same as above. They can be not right angles. If they are the same degree, they are congruent, so they do not have to be right angles, which makes this statement false.
Contrapositive: If angles are congruent, they will not both be right angles, because right angles are the same degree, which makes them congruent. Thus, this statement is true.
Step-by-step explanation:
Using SOHCAHTOA
Second Question Explanation:
a. The base angles of an isosceles triangle are equal so angle ABC is also 32°
but the sum of angles in a triangle = 180° therefore
let angle CAB be x
b. If you share a triangle in half you get 2 right angles so I'll use SOHCAHTOA to find the length AB
First the base of the right angled triangle will be 20/2 = 10
c. To find the are we'll need to get the height first
using the right angled triangle With base 10cm and hypotenuse 11. 8 to find the height we'll use the Pythagorean theorem
now to find the area
Answer:
3 times 1
Step-by-step explanation:
2.75 - 75 or in other words 7 is closer to 10 than 0, so well round it up to the next number, 3.
1.25 - 25 or in others words 2 is closer to 0 than 10, so we'll round it down to the nearest lowest whole number, 1.
our new expression: 3 × 1. hope that helps!
