Answer:
7x + 34 = 90
-34 -34
7x = 56
Divide by 7 on both sides:
X = 8 degrees
A right angle equals 90 degrees so that must mean angle 7x + 34 must equal to 90 so we solve for x.
A triangle equals = 180 degrees
A quadrilateral equals = 360 degrees
A right angle equals = 90 degrees
A straight line equals = 180 degrees
Answer is D) 2/3 because you divide the whole equation by 3 scene as 2cups=3gal. In order to get one gal, you need to divide the right side by 3 to make one and what you do to one side of an equation, you must do to the other.
Answer:
Place value can be defined as the value represented by a digit in a number on the basis of its position in the number.
Step-by-step explanation:
In the number 456, the "5" has a face value of 5. Value = The place value of the digit times its face value. Example: Find the value of the digits 6, 8 and 4 in the number 684.
Determine whether ∆DEF=∆JKL, given that D(2,0), E(5,0), F(5,5), J(3,-7), K(6,-7), and L(6,-2)

Answer:
Yes , triangle DEF is congruent to JKL
Step-by-step explanation:
Given:
The coordinates of triangle DEF are;
D (2, 0)
E(5. 0)
F(5, 5)
and
the coordinates of triangle JKL are:
J(3, -7)
K(6, -7)
L (6, -2)
The rule of translation is used on triangle DEF to get triangle JKL:
i.e
= J
= K
= L
As, we know that two triangles are known as congruent if there is an isometry mapping one of the triangles to the other.
therefore, triangle DEF congruent to triangle JKL
