There is 2 ways to solve this type of question.
Method 1
--------------------------------------------------
Formula
--------------------------------------------------
a² + b² = c²
--------------------------------------------------
Apply the formula
---------------------------------------------------
(7√2)² + (7√2)² = c²
c² = 98 + 98
c² = 196
c = √196
c = 14
--------------------------------------------------
Ans: The diagonal length is 14cm
--------------------------------------------------

Method 2
--------------------------------------------------
Identify the triangle
--------------------------------------------------
This is a special triangle
45° - 45° - 90°
--------------------------------------------------
Property of the Angles
--------------------------------------------------
x - x - x√2
--------------------------------------------------
Find hypotenuse
--------------------------------------------------
Given that the non-hypotenuse is 7√2
Hypotenuse = (7√2)(√2)
Hypotenuse = 7 x 2
Hypotenuse = = 14cm
--------------------------------------------------
Ans: The diagonal length is 14cm
--------------------------------------------------
You need the percentages to answer the question
Answer: Carla P. 15.1
Step-by-step explanation:
Y=mx+b ....formula of slope
m refers to slope and b is intercept,,,so this become equation of y.
now answer,
y=5/8x+b
Answer:
Ernie's time is 11.1 seconds
Explanation:
If Bert won the race with the time of 12.6 and the time difference is 1.5, this means Ernie's time was 1.5 seconds less than 12.6.
12.6
−
1.5
=
11.1
