The problem provides the measures of the three angles in a triangle labeled A, B, and C. Angle B is given as a constant value, while angles A and C are given as algebraic expressions involving a variable, x.<\/p>\n\n\n\n<p>The given angles are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Angle A = 8x<\/li>\n\n\n\n<li>Angle B = 50\u00b0<\/li>\n\n\n\n<li>Angle C = 4x + 10<\/li>\n<\/ul>\n\n\n\n<p>According to the angle sum theorem for triangles:<br>Angle A + Angle B + Angle C = 180\u00b0<\/p>\n\n\n\n<p>We can substitute the given expressions and value into this equation to solve for x:<br>(8x) + (50) + (4x + 10) = 180<\/p>\n\n\n\n<p>First, we simplify the equation by combining like terms. We add the terms with the variable x together (8x + 4x) and the constant numbers together (50 + 10):<br>12x + 60 = 180<\/p>\n\n\n\n<p>Next, to isolate the term with x, we subtract 60 from both sides of the equation:<br>12x = 180 &#8211; 60<br>12x = 120<\/p>\n\n\n\n<p>Now, we solve for x by dividing both sides of the equation by 12:<br>x = 120 \/ 12<br>x = 10<\/p>\n\n\n\n<p>With the value of x determined, we can now find the specific degree measures for Angle A and Angle C by substituting x = 10 back into their original expressions.<\/p>\n\n\n\n<p>For Angle A:<br>Angle A = 8x<br>Angle A = 8 * (10)<br>Angle A = 80\u00b0<\/p>\n\n\n\n<p>For Angle C:<br>Angle C = 4x + 10<br>Angle C = 4 * (10) + 10<br>Angle C = 40 + 10<br>Angle C = 50\u00b0<\/p>\n\n\n\n<p>To verify our solution, we can add the three angles to ensure they sum to 180\u00b0:<br>Angle A + Angle B + Angle C = 80\u00b0 + 50\u00b0 + 50\u00b0 = 180\u00b0.<br>The sum is correct, confirming our calculated values for angles A and C.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner6-1033.jpeg\" alt=\"\" class=\"wp-image-260049\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Find angles A, C.
